Is the “extra finger” trait dominant or recessive? How do you know?
Answer:
It is recessive.
Explanation:
Having an extra finger, also known as polydactyly, is relatively rare, and people with polydactyly are unlikely to have children with the trait unless both the mother and father both have it, making it a recessive trait.
Was the ancestor terrestrial, aquatic, or live on both land and in water?
Answer:
Starting about 375 million years ago, transitional “fishapods,” with both primitive, fish-like traits and adaptations for semi-aquatic living, begin to appear in the fossil record.

According to the Frank-Starling Law of the heart, as contraction strength increases the stroke volume ________. Group of answer choices decreases shows no change increases
We can confirm that this law tells us that both stroke volume and contraction strength increase at the same time.
What is the Frank-Starling Law of the heart?This law indicates the relationship between the volume of the ventricle, specifically the left ventricle, and the strength of its contractions. It follows the logical approach that if there is more volume in the ventricle, the cardiac muscles will have to stretch to allow for the space, which in turn causes a much stronger contraction when these muscles activate.
Therefore, we can confirm that this law tells us that both stroke volume and contraction strength increase at the same time.

Which best explains why it is difficult to classify protists?
Protists are difficult to characterize because of the great diversity of the kingdom. These organisms vary in body form, nutrition, and reproduction. They may be unicellular, colonial, or multicellular.
Why is it difficult to explain one certain way a protist reproduces?It is hard to demonstrate one certain way a protist reproduces :
Some protists use agamic reproduction at one stage in their life and then use gamic reproduction at another stage in their life.
Thus, Protists are difficult to characterize because of the great diversity of the kingdom.

In a mass extinction, many species become extinct at the same time. scientists have concluded that a mass extinction killed the dinosaurs and other species, in part as a result of an asteroid striking the planet. what pattern in the fossil record supports this conclusion?
The pattern in the fossil record which supports the idea of a mass extinction event is the sharp decrease in biodiversity in rock layers.
What is a mass extinction event?A mass extinction event is one which in which a large number of species of organisms die off due to natural or artificial causes.
A mass extinction events is concluded to have killed the dinosaurs and other species, in part as a result of an asteroid striking the planet.
The evidence for this in fossils records is that the lower, older rock layers contains a great diversity of fossil life forms, while the younger layer immediately above is contains few organisms in comparison.
Therefore, the sharp decrease in biodiversity in rock layers provides evidence for a mass extinction event.

Hello people ~
Animals from colder climates generally have shorter limbs. This is called
(a) Allen’s rule
(b) Johnson’s rule
(c) Arber’s rule
(d) Niche rule
Answer:
(a) Allen's rule
Explanation:
It is a heat-conservation mechanism that prevents heat loss from the body. Heat gain and heat loss can be maximised and minimised by lowering the surface area to volume ratio of the body. Small animals are uncommon in the polar regions due to their larger surface area and lower volume.
I am joyous to assist you at any time.
Answer:
Allen's rule
Explanation:
In colder climates they need more heat to warm their bodyIn order to not lose more heat from body they have shorter limbs by which they get lower surface areaWhat happens to a species if an environment changes and there are no variation

Consider the cross aa bb cc dd ee x aa bb cc dd ee. If these 5 allele pairs all assort independently, then the probability that any individual offspring will have the genotype aa bb cc dd ee is 1 out of.
If the allele pairs assort independently, the probability that any individual offspring will have the genotype aabbccddee would be 100% or 1 out of 1.
Independent assortmentSince the alleles assort independently, the gametes from each genotype will all be abcde.
Crossing abcde and abcde:

Define Photosynthesis.
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
