The genotyoe of the offspring can be obtained from the genotype of the parents using a punnet square.
What is genotype?The term genotype refers to the sum total of the genes that an organism receieves from its parents. We have to note that genes often occur in pairs called alleles. The combination of gene alleles controls the expressed trait in the organism.
This question is incomplete. However, we do know that the genotyoe of the offspring can be obtained from the genotype of the parents using a punnet square.

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:
abcde x abcde
aabbccddee
This means that all the progeny from the cross will be aabbccddee giving a 100% chance.

Carbohydrates are less-efficient fuel sources than fats because the carbon in carbohydrates is more:
Answer:Because complex carbohydrates are larger molecules than simple carbohydrates
Explanation:
Because complex carbohydrates are larger molecules than simple carbohydrates, they must be broken down into simple carbohydrates before they can be absorbed. Thus, they tend to provide energy to the body more slowly than simple carbohydrates but still more quickly than protein or fat.

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.

(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.

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.

What are muscles?Muscles are a special type of tissue that has the ability to contract in response to a given stimulus.
There are different three types of muscle fibers: cardiac muscle, skeletal muscle and smooth muscle.
Cardiac muscle and smooth muscle are involuntary muscles, whereas skeletal muscle is a voluntary muscle.

https://brainly.com/question/1283837
Answer:
Involuntary: Smooth
Voluntary: Skeletal
Electrical Nodes: Cardiac
Tendons: Skeletal
Digestive Tract: Smooth
Arteries: Smooth
Extensors: Skeletal
Explanation:
Types of muscles. The three kinds of muscle in the body are the skeletal muscle, the smooth muscle, and the cardiac muscle. The skeletal muscles are attached to the bones and allow one to move at will. Because the skeletal muscles are mostly under your conscious control, they are sometimes called "voluntary" muscles. Smooth muscle lines the inside of such hollow organs as the digestive system, bladder, and arteries. Smooth muscles work automatically and are beyond your conscious control. They are referred to as "involuntary" muscles. Cardiac muscle is unique to the heart.
Although skeletal muscles seem to be under your control, a lot happens of which you are not aware. First of all, your posture, even when asleep, is controlled by skeletal muscles without your paying much attention to it. Your mouth, for instance, would flap open if your brain did not maintain a certain tension in your chewing muscles all the time. Your chin would spend a lot of time resting on your chest if your neck muscles didn't hold your head up. And your movements of all kinds would be pitifully awkward if your cerebellum did not coordinate all the muscles necessary to perform even the simplest actions. Just scratching your nose, for instance, requires dozens of muscles to move in exactly the right way at exactly the right time. You are truly "fearfully and wonderfully made."
We will now take a closer look at the other two types of muscles. Skeletal muscles can be attached to other muscles or to bones either directly or by a thin band of connective tissue called a tendon. Do not confuse this tendon with a ligament, which connects bone to bone and not muscle to bone. Two good examples of tendons can be found in the back of your legs. One is the Achilles tendon which attaches the calf muscle in the lower back part of your leg to your heel. The other tendons are on the back side of your knee, called the hamstrings. They serve to attach muscles in the upper back part of the leg to the bones of the lower leg and flex your knee. Locate these structures on your own leg.
The point at which a muscle is attached to the less movable part of the body is called the origin. The point at which a muscle is attached to the more movable part of the body is called the insertion. The biceps muscle of your upper arm is a good example of both these points. The biceps has its origin in your shoulder and its insertion in the bones of the forearm.
Skeletal muscles differ relative to their effect on the body. Those muscles that bend a joint are called flexors, and those muscles that straighten a joint are called extensors. Muscles always work in pairs, one opposing the action of the other. For instance, the upper arm has biceps on the front, which serves as the flexor. The muscle that opposes this motion and serves as the extensor of the forearm is the triceps, which is located on the back of the upper arm. When one muscle contracts, the other must relax. Study the diagram and then see if you can feel the alternating contraction of the biceps and triceps in your own upper arm as you bend and straighten it.
You should be careful to get enough exercise to keep your muscles in good shape. Muscles will grow larger and have better tone, which means they will always be slightly contracted, if they are used. If a person is lazy or is confined to a bed or wheelchair for a prolonged period of time, the muscles not being used will become smaller and lose their tone. This condition is called atrophy. A muscle atrophies at a rate of about 1% a day, so that it will lose a full third of its strength after a month of disuse. Disuse also causes bones to soften by losing their calcium. "Use it or lose it" is a solid maxim of physiology.

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.
