Which of the following are pieces of evidence showing common ancestry among species?

Answers

Answer:

1. The pieces of evidence that support the theory of evolution include the following:

a. Fossil records/evidence

b. DNA of the organisms

c. Comparative anatomy

2. Whales have features that are similar to land mammals, such as the presence of hip bones and the need to breathe air. In this case, the whale fossils indicate that the modern whales that we see today have evolved from the land-dwelling mammals that existed 50 to 70 million years ago.

3. According to Darwin’s theory of evolution through the process of natural selection, the presence of a trait that is observed throughout the timeline of divergence of species is used as evidence that supports the idea that certain organisms share common ancestors.

In this case, comparative anatomy can provide the scientists the evidence that the organisms which share anatomical or structural similarities have common ancestry; hence, supporting the theory of evolution.

What type mutation are most harmful to an organism

Answers

Answer:

type 1

Explanation:

Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered.

a) they are made of many cells

b) they are made of one or more cells

c) they come from the same kind of cell

d) they come from noncellular structures

Answer:

The correct answer is - option b. they are made of one or more cells

Explanation:

The cell theory has three major parts that are; the cell is the basic and physiological unit of the organism, all living organisms are made up of one or more cells, new cells come from the pre-existing cells.

On the basis of the cell theory, we can say that all organisms including the cheetah that is a multicellular organism or paramecium a single-celled organism, are made up of one or more cells.

Use the same article to answer the following questions. Muscle Contraction What happens if there is not enough ATP available?

Answers

If there is not enough of ATP molecules available then, there is no muscle contraction.

What is Muscle contraction?

Adenosine triphosphate (ATP) is a way to store and also uses this energy in the breaking down the complex compounds which are present in the food that we eat. If there is not enough amount of ATP present, then this could lead to a lesser oxygen available in the cell on the food being eaten. Hence, this will affect the energy that we can get from a certain type of food particles.

Muscle contraction is the process of tightening, shortening, or lengthening of the muscles when a person do some type of activity. Muscle contraction can happen when a person can hold or pick up something, or when a person can stretch or exercise with weights.

Species that evolved in coral reef habitats always stay in those habitats. Coral reefs have much biodiversity, but most species that live there migrated from other habitats. Most organisms that live in coral reef habitats are zooxanthellae. More new species have evolved in coral reef habitats than in most other types of habitats.

Answers

Answer:

Most organisms that live in coral reef habitats are zooxanthellae.

Explanation:

zooxanthellae are the single-celled dinoflagellates that lives in mutual relationship with corals, jellyfish, and nudibranchs. These organisms have a mutualistic relationship between zooxanthellae and corals. Coral produces carbon dioxide and water in the process of cellular respiration while on the other hand, the zooxanthellae use this carbon dioxide and water to carry out photosynthesis for making their own food like plants so both the organisms get benefit from one another.
