Which does not provide for enhanced genetic mixing?
A.Mix-matching
B.Random segregation
C.Crossing over
D.Fertilization that occurs through sexual reproduction
Answer:
A. Mix-matching
Explanation:
Sexual reproduction increases genetic variation in offspring by three main mechanisms: 1-random assortment of chromosomes during meiosis 2-genetic recombination, and 3-random fusion of gametes from different parents. In the first place, the pairs of homologous chromosomes are randomly oriented in metaphase I before they separate in Anaphase I. In consequence, daughter gamete cells receive different combinations of chromosomes. Second, recombination (also called crossing over) refers to the interchange of genetic material between non-sister chromatids during prophase I, thereby also increasing genetic variation in daughter cells. Third, the fusion of two haploid cells (i.e., gametes) in diploid organisms results in the formation of a single zygote cell that develops into a new organism, thereby the process of random fertilization between any two gametes generates different diploid zygotes, increasing thus genetic diversity.

The sacrum articulates with the The sacrum articulates with the ilium and ischium. pubis. ilium. ischium and pubis. ischium.
Answer:
The sacrum articulates with the ilium.
Explanation:
The sacrum is a bone formed by the sacral vertebrae, which have fused to give this bone. Above it articulates with the lumbar vertebra, below with the coccyx, which is the last section of the vertebrae column. Lastly, it articulates with the ilium at the sides. The ilium is one of the three bones that makes the hip bone. It is the largest one and in the upper part of the hip bone.
The ischium and pubis, which are the other two bones that form the hip bone, do not articulate with the sacrum, but they articulate with the ilium and with each other.
The role played by the systems of the body in ensuring survival of farm animals in hot and dry climates
Answer:
Answer to the following question is as follows;
Explanation:
Domesticated animals have a natural instinct to seek out cover and seek refuge from the scorching heat. Their bodies, on the other hand, have inherent defensive systems to help them cope with heat and dryness. One of these is their covering or fur, which gives sun protection.
Animals living in hot, dry climates consume a lot of water, which is subsequently stored in their tissues to keep them from becoming dehydrated. Sweating is accomplished by certain animals by keeping their mouths open.

How does reproductive isolation cause speciation?
A. It flows interbreeding.
B. It stops adaptive radiation.
C. It reduces gene flow.
D. It prevents divergence.
Answer:
C. It’s reduces gene flow.
Explanation:
Reproductive isolation cause speciation as it reduces gene flow. Therefore, the correct option is C.
Mechanisms that prevent or restrict the exchange of genetic material (gene flow) between populations are called reproductive isolation. When reproductive isolation occurs, populations become genetically isolated from each other, resulting in different evolutionary paths. This may eventually lead to the speciation or evolution of new species. Reproductive isolation limits the exchange of genetic variation between populations by limiting gene flow. This means that genetic changes, such as mutations or genetic drift, that occur in one population do not affect other populations in the same way.
Therefore, the correct option is C.

Leaf is modified into thorn where water availability is low.....give reason?
Answer:
To help conserve water or prevent loss via transpiration from the leaves
Explanation:
Some plants are found growing in habitats with little or no moisture content as annual rainfall is very low. These plants are called xerophytic plants. However, despite the low water condition, these plants are adapted to the environment and still survive.
One of their adaptation (structural) is that their leaves are reduced to thorns. Ideally, plants tend to lose water via the stomata on the leaves in a process called TRANSPIRATION. Hence, the leaves of plants adapted to a xerophytic habitat is modified to thorns in order to prevent water loss from the leaves and conserve the water.

What is DNA?
DNA, or deoxyribonucleic acid, is the hereditary material in humans located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.
The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.
What is DNA Replication?In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.
DNA replication occurs in all living organisms acting as the most essential part for biological inheritance and it is essential for cell division during growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA.
The cell possesses the distinctive property of division, which makes replication of DNA essential.
DNA is made up of a double helix of two complementary strands. The double helix describes the appearance of a double-stranded DNA which is composed of two linear strands running opposite to each other and twist together to form.
During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication.
As a result of semi-conservative replication, the new helix will be composed of an original DNA strand as well as a newly synthesized strand.
Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.
What is the role of Helicases in DNA Replication?Helicases are enzymes that bind and remodel nucleic acid or nucleic acid protein complexes.
Helicases are of two types- DNA Helicases and RNA Helicases.
Role of Helicases:
- Separate the double stranded DNA into single one to allow copying.
- Initiate synthesis at the origin of unwinding
- Helicases use the energy stored in a molecule called ATP, which serves as the energy currency of cells, to break the bonds.
- DNA helicases also function in other cellular processes where double-stranded DNA must be separated, including DNA repair and transcription.
- RNA helicases are involved in shaping the form of RNA molecules, during all processes involving RNA, such as transcription, splicing, and translation.

A founding population usually has lower genetic diversity than the original population it came from. For those alleles that are shared by the two populations, how are allele frequencies different (or similar)
Answer:
In the founding population, the allele frequency is different from the original bigger-sized population. The size of the new population affects this difference even more. Some of the alleles will tend to increase, while some others will tend to decrease in frequency.
Explanation:
Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population.
Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population.
Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. The bottleneck effect most likely affects smaller populations.
Founder effect refers to the origin of a new population from only a few individuals that are coming from a bigger-sized population. These founder individuals, which are carrying some of the genes of the original population, settle down in a new area and reproduce. The new and small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition. When the number of individuals that originated the new population is low, the founder effect will be very extreme because the genetic drift effects are inversely proportional to the original number of individuals.

b.Compare the glucose levels of person 3 with the glucose levels of person 1, 2 hours after drinking 75g glucose.
c.Person 3 cannot produce the hormone that controls blood glucose levels. State the hormone that person 3 cannot produce.
Pic is the table to refer.
pls answer it is urgent
Answer:
See the answer below
Explanation:
a) From the table, the glucose level of person 1 (5.4) was less than the glucose level of person 2 (5.6) after 12 hours of fasting. The glucose level of person 1 falls within the normal fasting blood sugar range (3.9 to 5.6 mmol/L) while that of person 2 was borderline higher than normal.
b) Also from the table, the glucose level of person 3 (12.1) was greater than that of person 1 (6.4) when the glucose levels were measured 2 hours after drinking 75 g glucose. Normal after-meal sugar level ranges between 6 and 10.9 mmol/L. Hence, person 3 appears to be diabetic while person 1 seems normal.
c) The hormone that person 3 cannot produce is insulin.
Insulin helps lower blood sugar levels when necessary by signalling the liver to convert the excess sugar to glycogen which is then stored in the body. When the blood sugar falls below the normal range, another enzyme, glucagon, signals the liver to convert the glycogen back to sugar to compensate for the decrease.
