c. variation.
d. adaptation.

Answers

Answer 1

Answer: Of course the answer is
b. evolution

Answer 2

Answer:

Final answer:

In a biological context, 'change over time' refers to evolution. Evolution is a process by which living organisms have developed and diversified from earlier forms over time. Mutation, variation, and adaptation are components of this process.

Explanation:

The term 'change over time' in biology usually refers to the concept of evolution. Evolution can be defined as the process by which different kinds of living organisms have developed and diversified from earlier forms during the history of earth. This involves slow changes happening in species over long periods. This could be due to factors like genetic variation, environmental changes, and natural selection.

On the other hand, mutation, variation, and adaptation are components of evolution. A mutation is a change within the DNA of a gene. A variation represents the differences within a species, and adaptation is the process where an organism adjusts to its environment over time for survival.

According to a recent encyclopedia entry about dog breeds, Labrador retrievers come in two specific breeds: English and American. The article cites six studies from several scientific journals about dog breeding showing that males of both breeds usually average 29-41 kg (65-90 lb) in weight, and females usually average 25-32 kg (55-70 lb) in weight. Anna’s female Labrador retriever weighs 38 kg (83 lb). What does Anna’s dog’s weight indicate about the reliability of this source?

Answers

Final answer:

Anna's dog's weight falling outside the average range doesn't necessarily indicate the source is unreliable as it could be affected by individual variability. A broader sample would need to be assessed. Fur color, unrelated to weight, is determined by genotypes.

Explanation:

Anna's female Labrador Retriever being 38 kg (or 83 lb) falls outside the average weight reported in the encyclopedia for female Labradors, which is 25-32 kg (or 55-70 lb). However, these weights are averages and there can be exceptions due to factors such as individual genetics, diet and physical activity level. But, if a large number of Labrador Retrievers greatly exceed or fall below these averages, then it could indicate a problem with the reliability of the source. It's also important to cross-verify such information with other reliable sources. Meanwhile, the fur color is not associated with the weight, but based on alleles. For example, the ee_ genotype makes a Labrador yellow and B_E_ genotype turns it black.

Colorful, fossilized ancient trees that are now made of rock have undergone which type of preservation?

Answers

Good evening,

Living in California and having a forest made of trees just like this here, your answer is petrification (hope I spelled that right). This happens to organic materials where the original material and filling is replaced with minerals over time, fossilizing the material completely.

Hope this helps,
-Timmeh

Answer:

petrification

Explanation:

P450 encodes an enzyme that detoxifies insecticides. Abc8 encodes a transporter protein thatpumps insecticides out of cells. Cps encodes an external structural protein located in theexoskeleton that greatly reduces the absorption of insecticides. Based on this information andthe data in Figure 1, explain how a deletion of both P450 and Abc8 results in lower survival inbedbugs compared with a deletion of Cps only.

What happens to the body when you have Down Syndrome? Please explain!

Answers

As babies they may reach growth and development milestones later thanother children do. These may include rolling over, sitting,standing, walking, and talking. As children in this age group,health problems and developmental disabilities can lead tobehavior problems. For example, a child may develop oppositionaldefiant disorder which is a disorder in a child marked by defiant and disobedient behavior to authority figures.They may get this disorder because he orshe does not communicate well or understand others' expectations. As teens puberty startsat about the same ages for teens with Down syndrome as for other teens. They may face social difficulties and vulnerabilities such as abuse, injury, and other types of harm. They may also have ahard time handling strong emotions and feelings. Sometimes thesestruggles can lead to metal health problems,especially depression which could lead to self-harm or even suicide. As adults men with Down syndrome most often are sterile andcannot father children. Many women with Down syndrome can have children, andthey usually have early menopause which is a natural decline in reproductive hormones when a woman reaches her 40s or 50s but in this case it would usually happen early in Down Syndrome women.

A scientist is trying to determine the relationship between clams, snails, and squid. When she generates a molecular clock, she is surprised to see that clams and squid are more closely related than clams and snails. Which did the molecular clock data show?Clams and squid have been evolving separately for a longer time than clams and snails.

Clams and squid have been evolving separately for a shorter time than clams and snails.

Clams and snails have more in common genetically than clams and squid.

Clams and snails are more similar in related structures than clams and squids.

Answers

I think the last answer presents the truth reveled by the molecular clock. The statement is true, it claimed that clams and snails have stronger relationship than squids. The findings can be strengthened with the origin of their class. All of the said animals came from Phylum Mollusca which make these animals related, but stronger structural relationship can be identified with snails and squids because they are both in the Class Gastropoda. The squid came from Class Cephaloda which makes it more related with octopus and cuttlefishes.

its the last option (Clams and snails are more similar in related structures than clams and squids.)
