Weebugs get energy storage molecule from eating greenleafs. What change to the greenleaf population could decrease the number of births in the weebug population?
A) increase greenleafs
B) decrease greenleafs
A decrease in green leaves can decrease the number of Weebugs. Hence, option B is correct.
How do green leaves make energy?Green leaves are producers. They contain a pigment named chlorophyll which helps to trap sunlight which is required by the leaves to make food, and this process is called photosynthesis.
Green leaves take carbon-di-oxide, sunlight, and water, and in the presence of chlorophyll, glucose is produced and oxygen is released as a by-product. This process takes place in the chloroplast. There are four steps involved in photosynthesis that is Absorption of light, transfer of electrons, ATP production and carbon fixation,
These leaves are consumed by primary consumers such as Weebugs, and they get energy. A decrease in green leaves can decrease the number of Weebugs. Hence, option B is correct.

Explanation:
why do lichens and mosses get mostly replaced by larger plant species during succession
Answer:
Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize

Normal blood cells slide easily through narrow blood vessels. In sickle cell disease many red blood cells change to a crescent shape like a slender moon Crescent-shaped blood cells cause blockages in blood vessels These blockages decrease the transport of oxygen People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body Some people have one sickle cell gene and one normal gene They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the method of reproduction in humans result in people getting one copy of a sickle cell gene and one copy normal gene? Describe the process
Answer:
Explanation:
The method of reproduction in humans is sexual reproduction: a type of reproduction that occurs when new organisms are produced through the coming together of genetic information from two individuals of different sexes mostly a male and a female (egg cell and the sperm). The genetic information for making the blood cells; the red blood cells genes in particular exists on chromosomes in the nucleus of the sex cells (egg and sperm cell) also called the gametes. Basically, the DNA provides instructions for the production of mostly all of the body's needs.
The genes coding for the sickle cells which is the abnormal red cell is always inherited in the recessive form meaning both parent has to possess one copy each of the defective gene in their DNA. For humans to get one copy of a sickle cell gene and one copy normal gene; it means one of the parents gametes (be it male or female) contributed the defective chromosome and the other normal gene is contributed by the other parent during copulation giving rise to an individual that is heterozygous for the trait
For example, the sperm cell with the defective gene fertilizes the egg cell that has the normal copy of the gene producing an heterozgous individual.

What can scientists infer about the period of very early Earth from the fossilized remains of trees found under a lake?
Answer:There is a theory that terrestrial plants evolved from aquatic plants through a process of natural selection. Thus, by finding fossils of plants under the river, scientists may conclude that this theory is correct and that these fossils represent the ancestors of terrestrial plants.
The emergence of plants that survive on earth is a very important milestone for the planet, it is believed that these plants have evolved from green algae called Chlorophyta that have survived in marshy areas that had alternating periods of flooding and drought.Then the discovery of these fossils, through scientific experiments may conclude that the theory is correct
Explanation:
Answer:
The fossil record is the record of life on earth preserved in rock as fossils. The fossil record provides evidence of where types of plants and animals lived, how long they lived, how they died, and how they changed. It also tells us about Earth’s early environment and how it changed. The fossil record helps determine the age of rock formations by looking at how deep the fossils are buried in the rock. When a fossil is found above another fossil in a rock formation, the deeper fossil are considered older.

A mother has one allele for dimples and one allele for no dimples. How many
of her gametes will carry the allele for dimples?
A. 0%
B. 25%
C. 100%
D. 50%
Answer:

Explanation:
So the mother in the problem must have gotten her alleles from her mother and father. Who donated what we are not sure. All we know is that she got one allele for dimples and one allele for no dimples. These are part of the mother's somatic cell DNA. This DNA is duplicated during interphase, right before meiosis occurs as the mother begins to form her gametes, however.

Two short-tailed Manx cats are bred together. They produce 3 kittens with long tails 5 short tails and 2 without tails. From these results, how do you think tail length in these cats are inherited? Show the genotypes for both the parents and the offspring to support your answer.
Answer and Explanation:
There are three phenotypes, so it seems that this an example of incomplete dominance, with the short tail being the intermediate form between long-tail and no-tail. Incomplete dominance is a condition where neither of the alleles completely dominates over the other one. Dominant alleles cannot completely cover up the recessive alleles. Descendents possess an intermediate phenotype between the two parental phenotypes and not the dominant one, which would appear if this would be the case of complete dominance.
Available data:
Two short-tailed Manx cats are bred together. F1: 3 kittens with long tails, 5 short tails, and 2 without tails.The T gene might express the tail trait. T allele expresses long the tail and is dominant over t allele which expresses the absence of the tail.
So, homozygous dominant individuals, TT, are long-tailed animals
homozygous recessive individuals, tt, have no tail
Heterozygous individuals, Tt, are short-tailed animals, the intermediate form.
Cross: Two short-tailed Manx cats are bred together
Parental) Tt x Tt
Gametes) T t T t
Punnet Square) T t
T TT Tt
t Tt tt
F1) 1/4 TT = Long-tailed animals
2/4=1/2 Tt = Short-tailed animals
1/4 tt = untailed animals
The ratio 3:5:2 of the progeny in the example is close enough to the Mendelian ratio 1:2:1.
Answer:
This is a case of incomplete dominance. Consider the genotypes below:
LL - long tailed
Ll - short tailed
ll - no tail
The parent genotype is Ll. This means they have the ability to produce offspring with either of the 3 given phenotypes depending on the combination of alleles that get passed down. The cross would be the following way:
L l
L LL Ll
l Ll ll
There's a 25% chance of long-tail, 50% chance of short-tail and 25% chance of no-tail.

A newborn child was brought to the hospital nursery before he was marked with his parents' names. The hospital workers must use what they know
about genetic outcomes to determine whom the child belongs to. They use his traits to help them. The baby has freckles (F dominant), and attached
earlobes (I recessive). They believe that the baby most likely belongs to a couple in which the man has attached earlobes but no freckles. It is known that
the woman is heterozygous for freckles and earlobe type.
Complete the Punnett square below to determine the probability that the child belongs to this couple. List the possible combinations of the father's
alleles across the top and the possible combinations of the mother's alleles down the left side. Then write your answer in the space below. Include a

offspring?
a. 100% Rr
b. 50% RR, 50% Rr
c. 25% RR, 50% Rr, 25% rr
When two heterozygous parents (Rr) are crossed due to dominance effect offspring will be 25% RR, 50% Rr, 25% rr, hence c is correct option.
What is heterozygous parents?Heterozygous condition when parent having both the allele showing different trait of one character and one allele masks the trait of another allele.
When cross of heterozygous parents (Rr) x (Rr).
Gametes are R,r and R,r.
Genotype will be 25% RR, 50% Rr, and 25% rr.
Due to law of dominance, one allele R is dominant over the other allele during crossing over.
Cross of parents in punnet square is attched in image below.
Therefore, both the parents are heterozygous, so offsprings will be having genotype, 25% RR, 50% Rr, 25% rr, hence option c is correct.
