Answer:
Increase in high temperature.
Explanation:
The population of the thermophile bacteria increase at high temperature as compared to other bacteria at high temperature because thermophile bacteria needs high temperature for growth and survival. Thermophile bacteria that flourish at relatively high temperatures ranging from 41 to 122 °C (106 and 252 °F) so we can conclude that the thermophile bacteria increase in population in the high temperature conditions.

observe the given relation and fill in the blanks cucumber: tendril citrus: meiosis: reduction division mitosis:
Answer:
citrus: thorns
mitosis: equational division
Explanation:
From the relationship:
Tendrils are thread-like appendages found in most climbing plants. They primarily function as supporting organs for climbing plants (such as cucumber) by stretching out and twinning around physical supports. The equivalence of this in citrus is the thorn.
Meiosis is a reductional cell division in which the chromosome number of the daughter cells is half of that of the other cells. Mitosis is equational division because the chromosome number of the parent cell is the same as that of daughter cells.
Discuss the impact of development planning for economic development for a development country like Pakistan under what circumstances a country should go for short term medium term and long term plan (it is a economics question)
Answer:
Great impact.
Explanation:
There is a great impact of development planning for economic development for a country because this development planning is important for the growth of economy of the country. Without planning, goals of better economy can not be accomplished. A country should go for short term plan in order to solve the economic problem at that time while on the other hand, medium and long term plan is used by the country in order to solve the economic problem completely.
During the process of genetic recombination, crossing over occurs between two nonsister chromatids. DNA segments are exchanged between two nonsister chromatids during meiosis I. None of the above. maternal and paternal chromosomes pair and physically exchange DNA segments. All of the above.
Answer:
DNA segments are exchanged between two non-sister chromatids during meiosis I.
Explanation:
An exchange of chromosome segments or parts between non-sister homologous chromatids occurs which is also called crossing over. This crossing over occurs in the meiosis I that is responsible for the variation in the offspring produced. The formation of hybrid species occurs due to this exchanged of DNA segments between two non-sister chromatids.
In the Punnett square fill in the shaded boxes with the alleles of each parent use B for the dominant allele (black fur) and b for the recessive allele (white fur)
Answer:
Explanation:
Under the male put BB
Next to the female bb
then first row should be Bb Bb
second row should Bb Bb
Here, all the alleles of the black parent are dominant and are represented as BB, and those of the white parent are represented as bb, and they both are purebred dominant and recessive alleles that have produced all dominant black (Bb) offspring.
What is Punnett Square?A Punnett square is a diagram used to predict the possible outcomes of a genetic cross between two parents. In this case, the parents have different alleles for a gene that determines the color of their fur. The dominant allele B produces black fur, while the recessive allele b produces white fur. The Punnett square is arranged in a grid, with each box representing one possible genotype for the offspring. The top row and left-hand column of the grid represent the alleles that each parent can contribute to their offspring. In this case, both parents are purebred,as expressed below.
Hence, black parents are dominant and are represented as BB, and those of the white parent are represented as bb, and have produced all dominant black offspring.

When comparing the yield of ATP from the different stages of cellular respiration, which produces the greatest number of ATP
Answer:
The correct answer is - electron transport system.
Explanation:
There are 3 main stages of cellular respiration (aerobic) that are Glycolysis, the Kreb's Cycle and the ETS or Electron Transport Chain. The formation of energy in ATPare as follows:
Glycolysis - glucose > 2 Pyretic Acid Molecules =>2 ATP and Hydrogen
The Krebs Cycle - Citric Acid (a derivative of Pyruvic Acid) > 2 ATP in 4 cycles and Hydrogen, carbon dioxide and water.
The Electron Transport Chain > electron carrying Hydrogens > releases the energy as 4 ATP and water
Thus, the correct answer is - The Electron Transport Chain is the stage that produces most of the ATP during cellular respiration.
The plant coleus has three distinct leaf color phenotypes: green, white, and variegated (white and green mixed) the crosses are made as follows: female variegated leaves × male green leaves gives offspring with all variegated leaves female green leaves × male with white leaves gives offspring with all green leaves female with white leaves × male with variegated leaves gives offspring with all white leaves This is an example of ________.
Answer:
Cytoplasmic inheritance
Explanation:
female variegated leaves × male green leaves ⇒ all variegated leaves female green leaves × male with white leaves ⇒ all green leaves female with white leaves × male with variegated leaves ⇒ all white leavesFrom these crosses, we can notice that only the female´s phenotype is expressed in the progeny, independently of the male´s phenotype. Whenever this occurs, it is probably due to the action of cytoplasmic inheritance.
Extrachromosomal or cytoplasmic inheritance refers to hereditability transmission controlled by cytoplasmic genes.
This form of inheritance lays in genes that are out of the nucleus. Even though most of the DNI is located in the nucleus, information for some characters is placed in organelles in the cytoplasm, such as mitochondria and chloroplasts. These organelles have a well-defined portion of the total cellular genome.
When a female expresses a trait that is defined by genes in the organelles, the whole progeny expresses the same trait as the female.
Mitochondrial inheritance is mostly maternal, but recent studies have demonstrated that it might also be paternal.
The described experiment is an example of Cytoplasmic inheritance.
What do you mean by Phenotypes?Phenotypes may be defined as the appearance or manifestation of a character. Phenotypes are also known as traits.
Cytoplasmic inheritance reveals the phenotypes of offspring according to female parents. In this mode of inheritance, characters or traits are stored in the organelles like chloroplast, and mitochondria, as well as in the cytoplasm.
Therefore, the described experiment is an example of Cytoplasmic inheritance.

A Scientist discovers a chemical that she thinks might be a potential treatment for a certain type of cancer cell. In order to test her hypothesis, the scientist treats one plate of cancerous cells with the newly discovered chemical, and leaves another plate of cancerous cells untreated. After 7 days, the scientist measures the number of living cells in each plate. The scientist finds that the cells treated with the chemical have a lower survival rate than cells left untreated. The scientist further observes that the substance has an effect on the Rough endoplasmic reticulum (RER). How might disabling the rough ER potentially hurt the cancerous cells? Be specific in your answer. What is the dependent variable? What is the independent variable?
Answer:
Affecting the ER causes alteration in cell homeostasis and eventual death.Independent variable: Drug or chemicalDependent variable: Cancer cells survival.Explanation:
Hypothesis ⇒ A chemical ⇒ might be a potential treatment for cancer cells.
Experiment:
Treated ⇒ One plate of cancerous cells with the new chemicalUntreated ⇒ Another plate of cancerous cells with no chemical7 days later ⇒ the number of cells in each plate
Results:
Cells treated with the chemical have a lower survival rate than cells left untreated.
Treated plate ⇒ fewer cellsUntreated plate ⇒ more cellsChemical affects the Rough endoplasmic reticulum (RER)
----------------------------------------------------------------------------------------------------------
The endoplasmic reticulum is in charge of many cellular functions, such as protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction.
When the synthesizing protein gets in the Rough endoplasmic reticulum, it continues its building in the organelle. Finally, the protein suffers folding and the initial stages of glycosylation.
Once the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex for their final association with carbohydrates. Finally, protein leaves the Golgi complex and goes to its final destiny.
Any alteration in the intracellular environment
inevitably affects the organelle and its functions. When the organelle is not properly working, proteins synthesis is affected and, consequently, all the cellular activities. The affected cell homeostasis might be so altered that the cell ends dying.
If the drug affects the ER by altering its environment or directly affecting it, the organelle will fail to perform its functions, and the cell will eventually dye.

The independent and the dependent variables are the two principal factors needed in an experiment.
Independent variable: Refers to all the variables in an experiment that provoke a response in another variable. The independent variable changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter.
In the exposed example, the independent variable is the drug that affects the cancer cells. The researcher decides to apply it or not, and the concentrations in which the drug is.
Dependent variable: Refers to the variable that reacts to the changes produced in the independent variable. Depending on how the independent variable is modified, the dependent variable change. It is usually identified by the letter Y.
In the exposed example cell survival is the dependent variable. Cancer cells respond to the presence/absence of the chemical, and might differently respond to the varying concentration of the drug.

"All honey flora are plants, but all plants are not honey flora". Justify.
Answer:
Beekeeping is affected by adverse climatic conditions and availability of floral resources. This study aimed to survey and characterize the flora in São João do Piauí, a semi-arid region in Piauí, Brazil, and to identify species providing resources to bees. Flowering plants were observed for 18 months, and records were taken of flowering date, growth habit, visitation and resources collected by bees. Melissopalinological analysis of honey produced in the area was performed. A total of 67 flowering plant species were recorded, of which 49 were considered as bee plants, with a predominance of herbs and shrubs. The low rainfall reduces the number of flowering species, which makes important the conservation and multiplication of species which bloom in dry season, such as Ipomoea glabra, Myracrodruon urundeuva, Sida cordifolia and Ziziphus joazeiro, as well as species that contribute to honey production such as Mimosa tenuiflora, Mesosphaerum suaveolens and Croton sonderianus.

You may have heard through various media of an animal alleged to be the hybrid of a rabbit and a cat. Given that the cat (Felis domesticus) has a diploid chromosome number of 38 and a rabbit (Oryctolagus cuniculus) has a diploid chromosome number of 44, what would be the expected chromosome number in the somatic tissues of this alleged hybrid
Answer:
The correct answer is - 2n = 41 chromosomes.
Explanation:
It is given that the cat has a diploid chromosome number of 38 while the rabbit has a diploid number of 44 chromosomes and if they form a hybrid then their expected chromosome number in somatic cells would be -
Cat (2n=38) produces haploid gametes with 19 chromosomes (n-19).
Rabbit (2n=44) produces haploid gametes with 22 chromosomes(n=22)
19+22= 41 chromosomes in the particular hybrid as half number of chromosomes come from each parent.

A population of birds lives on a small island. Another population of the same species lives on the mainland. The
distance between the island and the mainland is too great for birds to fly back and forth. Recently, a series of
sandbars and tiny islands have formed between the island and the mainland.
Answer:
The birds can now reach the Island.
Explanation:
The birds can now reach the Island because there is a sandbars and tiny Islands where they can rest for sometime as well as feed on the insects present at that sandbars and tiny Islands. Before these sandbars and tiny islands, the birds can't reach to the mainland due to large distance between Island and mainland so they have no capability to fly such large distance until the tiny Island and sandbars are appeared in the ocean.
