Scientific evidence shows that modern dogs, wolves, and foxes all have a common ancestor. Further evidence shows that dogs are more closely related to wolves than to fixes. Which of the following observations provides the BEST evidence that dogs are more closely related to wolves than to foxes? *
A. The diets of dogs and wolves are more similar that the diets of dogs and foxes.
B. The lifespans of dogs and wolves are more similar than the lifespans of dogs and foxes.
C. The genetic sequences (DNA) of dogs and wolves are more similar than the genetic sequences of dogs and foxes.
D. The body sizes of dogs and wolves are more similar than the body sizes of dogs and foxes.

Answers

Answer 1

The observation that provides the best evidence that dogs are more related to wolves than to foxes is the DNA sequence of dogs and wolves being more similar than that of dogs and foxes.

The DNA is a molecule that stores the genetic information of organisms. Thus, closely related organisms have similar information on their DNA, usually indicated by similar nucleotide sequences.

Therefore, if dogs and wolves are more closely related in ancestry than dogs and foxes, the DNA sequence of dogs and wolves will be more similar than the DNA sequence of dogs and foxes.

What is the function of the valves in the lymphatic vessels?

Answers

Answer:

1. pick up any fluid that has escaped the blood vessels

2. return the escaped fluid to the heart

3. remove any foreign material from the lymph

Explanation:

Lymph vessels pick up any fluid that has escaped the blood vessels and return it to the heart. Lymph nodes remove any foreign material from the lymph (bacteria, viruses, tumors) and contain lymphocytes (WBC!!!)

The function of the valves is to bring the expelled fluid back to the heart.

Each and every fluid that had already exited the blood arteries is collected by lymphatic vessels as well as returned towards the heart. Lymph nodules filter out foreign particles from either the lymph as well as house lymphocytes.

Which statement illustrates bias in scientific research?(1 point)

A. A microbiologist publishes data funded by the National Institutes of Health that does not support their original hypothesis.

B. A botanist publishes data about plant growth that does not support their original hypothesis and is replicable.

C. An ecologist publishes data funded by a construction company which supports their original hypothesis that an endangered animal's territory is not endangered.

D. A zoologist publishes incomplete data on sloths which supports their original hypothesis and notes that more research is required.

Answers

Answer:

D

Explanation:

The statement that illustrates bias in scientific research is an ecologist publishes data funded by a construction company that supports their original hypothesis that endangered animal's territory is not endangered (option C)

In scientific research, bias can occur when the results or processes are manipulated on purpose. This usually occurs if:

The researcher wants the hypothesis to match the resultsThe researcher or sponsor has an economic interest

Scientific research occurs in situation B because it is convenient for the construction company to show that endangered animal's territory is not endangered as this would allow the company to build in certain areas and therefore, they are likely to manipulate the results of this research.

According to this, option B shows scientific bias. On the other hand, other options do not show bias because in these the results do not seem to be manipulated.

2. How are the kelp and the chemosynthetic bacteria of the
hydrothermal vents similar?
A. Both use energy from the sun to make food.
B. Both are primary producers.
C. Both are scavengers.
D. Both use hydrogen sulfide as an energy source.

Answers

Answer:

C. Both are primary producers.(THIS IS THE CORRECT ANSWER)

Explanation:

Chemosynthesis is a biological conversion of carbon molecules. These are found around the hydrothermal vents.

It is due to the bacteria feeds on the hydrogen sulfide that is coming out from the vents that are required as an energy tonic for the bacteria to survive and kelp also has similar requirements. Kelps forests are shelters for these bacteria and hence both are found near the source of energy.  

Hence the option B both are primary producers.

They have a nucleus and other membrane bound organelles.

Explanation:

hoped this helped :)

The characteristics that protists and fungi both have that make them eukaryotes is the possession of a membrane bound nucleus and other organelles.

EUKARYOTES:

Eukaryotic cells are cells that possess a membrane-bound nucleus to house their genetic material (DNA). Eukaryotes also possess other membrane bound organelles like mitochondria, golgi apparatus etc.

This feature particularly differentiates them from prokaryotic cells. Eukaryotic organisms include plants, animals, fungi, some protists etc.

Therefore, it can be said that the possession of a membrane bound nucleus and other organelles is the characteristics that makes fungi and protists be considered eukaryotes.

They have different sugars in their backbones

DNA is a double strand and RNA is a single strand

RNA replaces thymine with uricel

Answers

Answer:

I believe the answer is:

They both have different phosphate groups in their backbones

Option A is correct. DNA and RNA have the same phosphate groups in their backbones.

DNA is deoxyribonucleic acid. DNA contains deoxyribose sugar. DNA  is usually found in double strands. In DNA thymine is present.

RNA is ribonucleic acid. RNA contains ribose sugar. RNA is usually found in single strands. In RNA thymine is replaced by Uracil.

Nucleic acid is made up of phosphate group, ribose sugar, and nitrogenous bases.

Hence, options B, C, and D are incorrect.

Therefore, Option A is correct. DNA and RNA have the same phosphate groups in their backbones.

A tall, green plant with dominant alleles for both characteristics  have a genotype TTGG and its phenotype is tall and green.

Explanation:

For a given trait, the dominant allele of the allelic pair is represented in capital letters (T and G), while the recessive allele is represented in small letters (t and g).

In the case of this plant, whose phenotype is tall and green —both dominant characteristics— and considered pure because both alleles are dominant, the genotype is TTGG.

In the case of a hybrid, the phenotype would be the same but the genotype would be TtGg. A recessive phenotype would be ttgg.
