Hope this helps!!!!!! I tried my best to answer!
Darwin proposed that evolution could be explained by the differential survival of organisms following their naturally occurring variation—a process he termed "natural selection." According to this view, the offspring of organisms differ from one another and from their parents in ways that are heritable, which happen because of the change in DNA!

Anna applies a force of 84n Nto lift her baby nephew 2.0 m. How much work
does Anna do? Answer
Answers
Answer:
168 J
Explanation:
Work can be calculated using the following formula.
w=f*d
where w is work, f is force, and d is distance.
Anna applied a force of 84 Newtons, and lifted the baby 2.0 meters.
f=84 N
d=2 m
Substitute these variables into the formula.
w=84 N* 2 m
Multiply
w=168 N-m
A N-m is the same as a Joule, or J.
w= 168 Joules
Anna does 168 Joules of work.

What was a constraint (a limitation or a condition) in this version?
Answers
Answer:
As seen in the question above, "constraint" is a word that indicates a limitation or condition. In this case, we can say that the "restriction" is an imposition to a limit under a given situation, and it can also mean an imposition of the free execution of an activity, skill and even limitation and a conditioning factor to a certain freedom.

Which statement best describes Mendelian or complete dominance?
When both the dominant and recessive allele shows.
When the dominant and recessive alleles mix to form a third phenotype.
When the dominant trait or allele completely masks the recessive allele.
Answers
Answer:
When the dominant trait or allele completely masks the recessive allele
Explanation:
Mendelian or complete dominance is a relationship of genes in which one allele of a gene pair that codes for a trait expresses itself over the other allele of the gene pair. The allele of the gene pair that expresses itself over the other is the dominant trait or allele, which completely mask the expression of the other allele called the recessive allele or trait.
In the pea plant experiment conducted by Mendel, complete dominance can be seen. For example, for seed color of pea plant, allele for yellow seed color was dominant over allele for green seed color.

Most scientists agree that saturated fats contribute to high levels of “bad” cholesterol, while monounsaturated fats and polyunsaturated fats lower this type of cholesterol. The table below shows data about fats in some common foods.
Food (14 g) Saturated fat (g) Monounsaturated fat (g) Polyunsaturated fat (g)
Canola oil 1.0 8.9 3.9
Margarine 1.6 5.4 3.4
Olive oil 1.9 9.9 1.4
Lard 5.0 5.8 1.4
Butter 7.9 3.7 0.5
Joyce and Linda are identical twins who are 50 years old and enjoy exercising daily. Joyce avoids eating any dairy or animal products and eats granola made with canola oil for breakfast. Linda prefers rich foods, and eats bacon, eggs, and buttered toast each morning. Which statement describes a logical inference that can be made from the provided information?
a)Butter has higher levels of saturated fats in it than canola oil.
b)Linda and Joyce both have high levels of “bad” cholesterol.
c)Butter contains a small amount of polyunsaturated fats.
d)Linda has a higher level of “bad” cholesterol than Joyce.
Answers
Answer: D: Linda has a higher level of "bad" Cholesterol than Joyce
Explanation: From the first sentence Saturated fat contributes to high level of bad cholesterol. Buttered food, bacon ( Lard) are significantly high in saturated fat which contributes to high level of bad cholesterol and that's what Linda is eating. Joyce on the other hand avoids animal products and feeds on granola from Canola oil which is low in saturated fat.
The logical conclusion base on this diet is Joyce has low level of bad cholesterol while Linda has high level of bad cholesterol

When are two populations likely to have very similar allele frequencies?
A. If the selective pressures are different
B. If there is a high mutation rate
C. If there is a large amount of genetic drift
D. If there is a large amount of gene flow
Answers
Answer:
c). If there was a large amount of genetic drift.
If the price of gene drift is excessive enough, then two populations will have equivalent allele frequencies and consequently can be taken into consideration as a single powerful population.
What causes allele frequencies to live equally?Allele frequencies continue to be constant over the years due to the following: there is no considerable price of a brand new mutation. individuals with all genotypes are similarly able to mate and pass on their genes; that is, there's no choice against any precise genotype.
What are two impacts of allele frequencies of a population?The natural choice, genetic drift, and gene go with the flow are the mechanisms that purpose modifications in allele frequencies through the years. while one or greater of those forces are appearing in a populace, the populace violates the Hardy-Weinberg assumptions, and evolution occurs.

Which type of tissue carries messages?
A. Nervous tissue
B. Connective tissue
C. Muscle tissue
D. Epithelial tissue
SUBN
Answers
Answer:
Nervous tissue
Nervous tissue is responsible for carrying messages throughout the body. It is made up of specialized cells called neurons, which are able to transmit electrical signals. These signals allow the body to respond to stimuli and coordinate its movements. Hence option A is correct.
Connective tissue provides support and structure to the body. It is made up of cells that are embedded in a matrix of fibers. The fibers can be made of collagen, elastin, or other proteins. Connective tissue can be found in many different parts of the body, including the bones, muscles, and skin.
Muscle tissue is responsible for movement. It is made up of cells that can contract and relax. There are three types of muscle tissue: skeletal muscle, smooth muscle, and cardiac muscle.
Skeletal muscle is attached to bones and is responsible for voluntary movement. Smooth muscle is found in the walls of internal organs and is responsible for involuntary movement. Cardiac muscle is found in the heart and is responsible for pumping blood.
Epithelial tissue covers the body and lines internal organs. It is made up of cells that are tightly packed together. Epithelial tissue protects the body from infection and helps to regulate body temperature.
