Answer: Some carnivores, called obligate carnivores, depend only on meat for survival. Their bodies cannot digest plants properly. Plants do not provide enough nutrients for obligate carnivores.
Explanation: so yes
Answer:
This answer varies.
Carnivores consume only meat-based nutrition, yes, however the prey that they devour may rely on plants as its food source.
You can say that carnivores do not directly rely on plants for their nutrition, but their prey might.

The main functions of this human body system is to -
A. detect odors in the environment
B. exchange gases with the environment
C. chew food as it enters the mouth
D. trap particles that enter the nose
E. trap particles that enter the nose
Answer:
B.
Explanation:
The human body system drawn in the picture is the respiratory system.
The respiratory system is the system of the human body that enables a human to respire or exchange gases with the environment. The respiratory system includes airways, lungs, trachea, nasal cavities, and pharynx.
The primary organ in the respiratory system is the lungs that assist in the exchange of gases.
Therefore, option B is the correct answer.
In Drosophila, the dominant allele Cy (Curly) results in curly wings. The cross Cy/ x Cy/ (where represents the wildtype allele of Cy) results in a ratio of 2 curly : 1 wildtype F1 progeny. The cross between the curly F1 progeny also gives a ratio of 2 curly : 1 wildtype F2 progeny. How can this result best be explained
Answer:
d
Explanation:
Using a Punnet square to represent the given information
The cross between Cy + and Cy + can be computed as:
Cy +
Cy Cy Cy Cy +
+ Cy + ++
From what we see above, it is above that the ratio of Curly to wildtype is in the ratio of 2:1
This illustrates that the genotype Cy Cy is lethal. This is explained when two curly F1 are crossed which resulted in the same ratio.
Hence, the inheritance of Cy/Cy is fatal.
What is the difference between an instinct and a learned behavior?
Answer:
See below.
Explanation:
The major difference between an instinct and a learned behavior is how it was picked up. An instinct is something that you're born knowing (think of being programmed to do certain actions or display specific behaviors.) An example of this would be how homing pigeons are "wired" and remember their home when they migrate. A learned behavior, on the other hand, is something you have to learn as you don't have a certain behavior, skill, etc. This can be a language, how to walk/talk, personality, likes and dislikes, learning how to read, write, or learn information. So right now, learning about this is displaying a learned behavior (being able to process information and read). :)
What type of heredity is shown in the pedigree?
A
sex linked dominant
B
sex linkęd recessive
С
autosomal dominant
D
autosomal recessive
The type of heredity is shown in the pedigree is autosomal recessive. Hence option D is correct.
What is heredity?Heredity is defined as the whole of biological mechanisms via which certain traits are passed down from one generation to the next. The system by which traits, similarities, and differences are passed down from one generation to the next is called heredity. A guiding biological principle, heredity explains why children resemble but differ from their parents.
Autosomal recessive is defined as when one variant is found on both alleles of a particular gene, a genetic condition is present. The disease must be autosomal recessive if any affected founding daughter has two unaffected parents. Both parents must possess the recessive gene in order for the affected person to inherit it from them.
Thus, the type of heredity is shown in the pedigree is autosomal recessive. Hence option D is correct.

In cats, coat color is determined by allelic variation at a single autosomal locus, with black fur dominant to white fur. Two heterozygous black cats are mated. What would be the probability of the following combinations of offspring in a litter of eight kittens?
a) All with black fur.
b) Five with black fur and three with white fur.
c) At least three of the kittens having white fur.
d) The firstborn kitten with white fur, and among the remaining seven kittens, three with black fur and four with white fur.
Answer:
Explanation:
Two Heterozygous Black cats mated
let 'B' be for the Black allele and 'b' for the white allele
hence the mating will be : Bb * Bb = BB , Bb , Bb, bb, BB, Bb, Bb, bb
a) Determine the probability that all kittens out of 8 kittens are black
That means the kittens will have 'BB' or 'Bb' alleles
probability of Black fur = 3/4
b) probability of 5 black and 3 white
probability of black = 3/4
probability of white = 1/4
hence probability of 5 black = 3/4 * 5 =

selection
Environmental conditions often favor one__
over another.
Answer:
phenotype or trait
Explanation: if it is really cold a mouse with thicker fur (phenotype) will do better
Environmental conditions often favor one selection over another.
In the context of evolution, selection refers to the process by which certain traits or characteristics become more or less common in a population over time. This process occurs due to environmental conditions that favor certain individuals with advantageous traits, leading to their increased survival and reproduction.
For example, consider a population of birds living in a forest with two distinct color morphs: light and dark. If the forest becomes darker due to increased tree cover, the dark-colored birds might be better camouflaged and have a higher chance of surviving and reproducing. Over time, the proportion of dark-colored birds in the population would increase, as they have a selective advantage in the new environmental conditions.
Similarly, if the forest becomes lighter, the light-colored birds may become more successful in avoiding predation and finding mates. In this case, the environmental conditions would favor the light-colored birds, leading to an increase in their frequency within the population.
Therefore, the term "selection" refers to the process by which environmental conditions favor certain individuals or traits, resulting in changes in the frequency of those traits within a population over time.

Why would water move faster through one kind of tree compared to another, and what might that tell us about their life cycle and susceptibility to environmental changes?
Answer:
Due to the presence of larger vessels.
Explanation:
Due to the presence of larger vessels of hardwoods in the tree, water move faster in that tree as compared to other type of plants. in smaller plants, small vessels are present which able them to move less amount of water as compared to large trees which have large vessels. It tells us that the tree adopted the environmental changes so that's why to overcome the change, they use more water.
