Answer:

A current scientific theory would be revised based on the new findings.

Explanation:

If new findings came about and challenged the current theory of natural selection so that Darwin's theory didn't look like it was true at all, the initial theory(darwin's theory of natural selection) would not be entirely discarded but revised according to these new findings and then form a sort of backbone to this new theory which would be based on findings of many independent researchers and not just one. Example: how some of Sigmund Freud's theories or Aristotle's may not be entirely valid today but still works as a fundamental for understanding other theories.

Answers

Answer:

The correct answer is D.

Explanation:

The plants are grouped formally into 12 phyla (phylum plural) and are collected in four groupings. These four groupings are based on the history of the evolution of important plant characteristics:

Nonvascular plants evolved earliest. They are distinct from the algae because they preserve the embryo inside of the reproductive structure after fertilization. There is no vascular tissue, xylem, and phloem for these plants to convey nutrients, water, and food. For example, moose, liverwort, and hornworts. These plants do not grow very high without vascular tissue.Vascular seedless plants have evolved into non-vascular tissue but no seeds. The fern, fern, club moss, and horsetails are examples. These plants could grow larger with vascular tissue.Gymnosperms have evolved into seeds but have no blooms. For example, redwood, fir, and cypress trees. Gymnosperms. Gymnos in Greek means "naked"; the gymnosperm seeds are bare, not floral.Flowers or angiosperms have developed into vascular tissue, seeds, and flowers. Angiosperm for example includes magnolia, roses, tulips, and tomatoes.

protection
growth regulation

Answers

Answer:

protection

Explanation:

The correct answer would be protection.

Goblet cells are special cells found in the epithelial layers of small and large intestines and some other organs such as those associated with the respiratory tracts. They secrete mucin and create a protective mucous layer in the walls of the intestines.

Lacrimal glands on the other hand are exocrine glands found in the eyes. They secrete the watery component of the eyes which is made up of water, electrolytes, and protein. The fluid produced by the glands protects the eyes from drying out.

Hence, both goblet cells and lacrimal glands serve protective functions.

All humans have shared biological needs, such as a need for food. However, in China people have an aversion to cheese, a food that is highly desired in the United States; and in the United States most people would find snake or dog meat inedible, even though both are enjoyed in China. How can this be explained

Answers

Answer:

The dietary differences between China and the US can be explained by the cultural, social and economic background that each of these countries had.

Explanation:

The main difference in food between countries is due to the culture of each country. This culture determines which elements are apt to be consumed and which are not. An example of this is dog food in China, which is very cultural, while the US and most Western countries do not welcome dog food because of its cultural context. Another example can be seen in the feeding of guinea-pig meat in Peru, however, other Latin American countries do not appreciate this type of meat.

The economic and social history of countries can also cause dietary differences. This is because these two factors change society and promote access to more modern and archaic foods.

Right atrium, right ventricle, lungs, left atrium, left ventricle, body.

Answers

Answer:

answer is D

l

Explanation:

Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.

The statement that describes the order blood flows through the body and the heart is:

Right atrium, right ventricle, lungs, left atrium, left ventricle, body.

What is blood?

It is a red liquid with different shades that varies according to the amount of oxygen it has inside, that is, hemoglobin.

Characteristics of blood circulation

It is a necessary substance for oxygenation to occur between cells, as well as to regulate blood pressure.

Each side of the heart is divided into an upper chamber called the atrium and a larger, lower chamber called the ventricle.

The blood flows since it has left the right ventricle, has been oxygenated by the lungs and has returned to the left atrium through the pulmonary veins, it is carried to the left ventricle.

Therefore, we can conclude that the main function of the blood is to ensure that oxygen and nutrients are distributed between the cells of each organism.

Insects: Please choose the correct answer from the following choices, and then select the submit answer button. typically have a younger flying life stage and an older aquatic life stage after metamorphosis. generally give birth to live young. typically mate and produce young during their larval stage. have a respiratory system with spiracles connecting to tracheae.

Answers

Answer:

The correct option is ( have a respiratory system with spiracles connecting to tracheae).

Explanation:

The class INSECTA are under the phylum arthropoda which is the largest phylum in the animal kingdom. The insects are mainly land animals, they are widespread and adapted to all types of environment. They are also the only invertebrates that can fly. Examples of insects include: ants, butterflies, beetles, aphids and grasshoppers.

An insect has a well-defined head, thorax and an abdomen. The head had six segments and bears a pair of jointed antennae, compound eyes, simple eyes and mouthparts. The thorax had three segments, each bearing a pair of jointed walking legs. The abdomen has eleven segments and may have sensory and reproductive structures.

An insect carries out gaseous exchange by means of a network of open air tubes or TRACHEAE inside it's body. These tubes have openings called SPIRACLES to the exterior. Therefore the insects have an respiratory system with spiracles connecting to tracheae.

In the Punnett square fill in the shaded boxes with the alleles of each parent use B for the dominant allele (black fur) and b for the recessive allele (white fur)

Answers

Answer:

Explanation:

Under the male put BB

Next to the female bb

then first row should be Bb Bb

second row should Bb Bb

Here, all the alleles of the black parent are dominant and are represented as BB, and those of the white parent are represented as bb, and they both are purebred dominant and recessive alleles that have produced all dominant black (Bb) offspring.

What is Punnett Square?

A Punnett square is a diagram used to predict the possible outcomes of a genetic cross between two parents. In this case, the parents have different alleles for a gene that determines the color of their fur. The dominant allele B produces black fur, while the recessive allele b produces white fur. The Punnett square is arranged in a grid, with each box representing one possible genotype for the offspring. The top row and left-hand column of the grid represent the alleles that each parent can contribute to their offspring. In this case, both parents are purebred,as expressed below.

Hence, black parents are dominant and are represented as BB, and those of the white parent are represented as bb, and have produced all dominant black offspring.

If two individuals were heterozygous for freckles, which are a dominant autosomal trait, what percentage of their offspring would you expect to have freckles

Answers

Answer:

75%

Explanation:

Firstly, an autosomal dominant trait is a trait the becomes expressed in the presence of only one affected allele, which is the dominant allele. Freckles is said to be an autosomal dominant trait meaning that the presence of the dominant allele (F) makes a person have the condition.

According to this question, If two individuals that are heterozygous for freckles cross i.e. Ff × Ff, the following proportion of offsprings will be produced: FF, Ff, Ff and ff (see punnet square).

From the genotypic observation of the produced offsprings:

FF, Ff - possess freckles

ff - do not possess freckles

Since, 3 (FF, Ff and Ff) of 4 offsprings possess freckles, the percentage of offsprings expected to have the condition will be:

3/4 × 100 = 75%
