Humans and dogs evolved from a common ancestor. Which pieces of evidence would support this? Check all that apply. Both of their adult forms look very similar. They both had a tail as an embryo. Their arm and leg structure is similar, but may have a different function. There are fossils of an organism that is half man, half dog in the fossil record. Both had gill slits when they were born.

Answers

Answer:

They both had a tail as an embryo.

Explanation:

Both human and dogs have tail as an embryo. Temporary tail-like structures are present in the human embryo. These tail like structure develop around the fifth or sixth week of gestation, having about 10 to 12 vertebrae and removed when it reached to its full development stage while on the other hand, tail present in dog's embryo also developed with time and we can see when the dog baby is fully formed.

Answer:

They both had a tail as an embryo.

Their arm and leg structure is similar but may have a different function.

Explanation:

They both had a tail as an embryo.

Vestigial structures are those body parts that have lost or reduced their original function during the evolution of a species. These vestigial structures might be found in many animals, including human beings. Vestigial structures were plenty functional for common ancestors. But with evolution, they degenerated, stunted, and became rudimentary for some of the new species.  

During the first 4 months of embryogenesis, all mammals have a tail at some point in their development. Dogs develop this structure and keep it during their whole lives, but humans lose it with time during embryogenesis. The tail disappears, and its forming vertebras get fussed with each other composing the coccyx, which represents a vestigial structure. This tailbone is the remnant of a missing tail.

In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, the coccyx, located at the end of the vertebral column, has lost this original function.

Their arm and leg structure is similar but may have a different function.

The fact that whales, humans, and dogs all have the same bones in the same order, but they matured differently in later embryological development, is an example of homologous characters.  

Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.  

These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.  

These homologous characters are common in organisms related and that share a common ancestor.

taj incorrectly states that autographs are also known as consumers that need to feed on other organisms, including plants and animals, to gain energy. which of the following best describes consumers that feed on other organisms such as plants and animals for energy?

A. carnivores
B. trophic levels
C. heterotrophs
D. herbivores

Answers

the answer is D) herbivores

Herbivores best describes consumers that feed on other organisms such as plants and animals for energy.

What do you mean by herbivores?

A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet.

Many herbivores have large, dull, flat teeth. These teeth are excellent for chewing and breaking down tough plant material. Carnivores have sharp, narrow teeth that are better for biting and tearing flesh. However, some herbivores also have strong, sharp teeth.

Examples of large herbivores include cows, elk, and buffalo. These animals eat grass, tree bark, aquatic vegetation, and shrubby growth. Herbivores can also be medium-sized animals such as sheep and goats, which eat shrubby vegetation and grasses.

Explain how an organ and organelles are related

Answers

Answer:

Just as organs are separate body parts that perform certain functions in the human body, organelles are microscopic sub-units that perform specific functions within individual cells. Organelles are specialized structures that perform various jobs inside cells.

Organelles are microscopic subunits that carry out certain tasks within individual cells, whereas organs are distinct body sections that carry out specialized tasks for the human body.

What is the relation between organ and organelles?

Literally, the phrase refers to “tiny organs.” Organelles provide specialized functions to keep a cell alive, much like organs like the heart, liver, stomach, and kidneys serve specific functions to keep an individual alive.

Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the major levels of organization in the body, going from the simplest to the most complex.

Like an organ in the body, an organelle is a subcellular structure that performs one or more particular functions for the cell.

Therefore, organ and organelles differ in their functioning.

Calculate the mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2​

Answers

Answer:

40kg

Explanation:

F=M*A

M=F\A

M=400\10

M=40kg

The mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2​ is 40 kg.

What is acceleration due to gravity?

The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g.

It is a vector quantity whose direction, strength, or magnitude match a plumb bob.

According to Newton's second law, an object's acceleration is inversely proportional to its mass and directly connected to the net force. An object's acceleration is determined by two factors: force and mass.

We know that,

F = m x g

m = f/g

Where,

F = force

m = mass

g = acceleration due to gravity

Given that,

F = 400N.

g = [tex]10m/s^2[/tex]

So,

m = 400/10

m = 40 kg.

Thus, the mass is 40 kg.

The diagram shows four pairs of chromosomes from the karyotype of a normal human male.
Select the pair of sex chromosomes.

Answers

Answer:

According to the karyotype image, the sex chromosomes of a normal human male are those of the last picture, where both are different.

Explanation:

The sex chromosomes are those that determine the sex in a species, as in the human being and other species X and Y. XY chromosomes determine the male sex while the XX sex pair corresponds to the female sex.

In humans, the chromosomes are grouped by pairs with the same characteristics, that is, most pairs of chromosomes are identical. The only exception is represented by the male human sex chromosomes X and Y. This difference in the sex chromosomes causes the different sex chromosomes (picture) to be called heterogametic.

Under certain external conditions, a person will perspire a great deal. For which internal condition does this response primarily provide homeostasis?

Answers

Answer:

Abnormally high temperature

Explanation:

Sweating or perspiration is a homeostatic response to abnormally high body temperature. Evaporation of the sweat causes cooling of the body and this causes the temperature of the body to return back to normal.

When the setpoint temperature of the body is breached by being too high, the negative feedback mechanism kicks-in, and the sweat glands of the skin becomes activated. The body sweats, and the evaporation of the sweat from the surface of the skin causes cooling and a return back to the setpoint.

16. In which of the following situations are the phenotypes of F2 offspring expected to follow
the ratio of 9:3:3:1?
a. monohybrid cross for two unlinked traits
b. a monohybrid cross for two closely linked traits
c. a dihybrid cross for two unlinked traits
d. a dihybrid cross for two closely linked traits​

Answers

Answer:

C

Explanation:

The F2 offspring of a cross would follow the ratio of 9:3:3:1 only if the cross is a dihybrid for two unlinked traits.

There is nothing like a monohybrid cross for two traits. A cross involving two traits is a dihybrid cross. Hence, options a and b are out of the equation.

A dihybrid cross for two closely linked traits would produce F2 offspring in another ratio that is different from 9:3:3:1 depending on the linkage map.

Hence, the correct option is C.

C.
has different alleles on the chromosomes in a chromosome pair.
D.
has extra alleles on both chromosomes in a chromosome pair.

Answers

Answer: C.

has different alleles on the chromosomes in a chromosome pair

Explanation:

Hetero means different.

A heterozygous condition is one in which the child inherits various eye-color genes from both biological parents. For that particular gene, a heterozygous genotype exists when there are two distinct versions. Thus, option C is correct.

What is the particular trait for heterozygous organism?

When two distinct alleles of a gene (one mutant allele and one wild-type allele) are present in a diploid organism's cells, that organism is said to be heterozygous at that particular gene locus.

Heterozygosity describes a particular genotype, since the cell or organism is referred to be a heterozygote just for the particular allele in question.

The heterozygote may, however, occasionally have a phenotype that is somewhere between the phenotypes of both homozygous parents.

Therefore, has different alleles on the chromosomes in a chromosome pair.
