Answer:

The correct answer is -

Euglena - single-cell organism

Onion bulb - organ

Blood - tissue (connective tissue)

Explanation:

The level of organization of an organ, or organism could be cellular level, tissue level, the organ level, organ system, or a complete organism. These levels are formed by assembling the lower level of the organization.

Euglena is a single-cell eukaryotic organism found in freshwater. These organisms have a very simple level of an organism which is cellular level. The onion bulb is the organ of the onion plant composed of shortened, compressed, underground stems (tissue) that are an organ-level organization.

The blood is considered as connective tissue due to the blood cells present in the matrix called plasm thus, blood is connective tissue.

Answer:

Since oxygen has a higher electronegativity than hydrogen, the electrons of the molecule tend to group closer to the oxygen than to the hydrogen atoms. as well as , water is said to be a "polar" molecule, which means that there is an uneven distribution of electron density.

Explanation:

Answer:Because the peripheral nervous system transmit reflex impulses from sense organs to central nervous system and then back to the sense organs. So both the Central nervous system and the peripheral systems are involved.

To understand a bit better.....

One of our body parts consists of a nervous system it is a complex network of neurons and cells that carry pieces of information to and from the brain and spinal cord to various parts of the body.

So in conclusion...

Yes! The Central nervous system and the peripheral systems are involved!So therefore your question is correct!

Hope this helps!

Answer:

If eagles died of disease, the number of snakes that prey on rats will increase, which will decrease the number of rats. Also, eagles will cause the and rabbit population to increase, decreasing the plant population and therefore decreasing the rat population because of the lack of food.

tldr; rats will decrease if eagles died of disease.

Answer:

The rabbit population willl increase because the eagles are not present to feaast on them. The population of the snake will also increase since the Eagles are not present and the rat's population will increase as welll because it's only 1 animal who is eating them.

Answer:

Each daughter cell contains the same genetic makeup as the original parent cell

Explanation:

After the process of mitosis and cell division 2 new identical daughter cells are created. Each daughter cells contains the same number of chromosomes as the original cell. Therefore, each daughter cell has a complete copy of all the genes that the original cell contained. Making them identical to the original cell.

Answer:

The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.

Explanation:

The picture in the  different stages in the life of a pea plant shows the grow of pea plant.

A pisum-family leguminous plant having tiny white flowers as well as long, green pods that yield tasty green seeds.

The four stages of something like the plant life cycle are seed, sprout, small plant, as well as adult plant. The seed would begin to grow into a little sprout once it is inserted into the soil, along with water as well as sunlight.

Therefore, the picture in the  different stages in the life of a pea plant shows the grow of pea plant.

1) The flu is caused by influenza viruses that infect the and people assume it's the flu because nose, throat, and lungs. These viruses spread when people with flu cough, sneeze or talk, sending droplets with the virus into the air and potentially into the mouths or noses of people who are nearby.

2)

3) yes because they don't always know signals can have symptoms as others and they assume it as flu because it is a known sickness

4)The flu, also known as the influenza virus, is diagnosed year-round in the United States. Fall and winter seasons are when the greatest impact is usually seen and, therefore, is considered the "flu season." Influenza activity has a period of greatest activity between December and February, but the activity can last until May.

Every year at the beginning of the fall season, people are encouraged to get a flu shot.

CDC data on influenza vaccine:

• 116 million doses of influenza vaccines have been distributed.

CDC

(Centers for Disease Control and Prevention) recommends that all persons 6 months and older receive the influenza vaccine at the end of October.

• Influenza vaccination offers important benefits

A flu is a common viral infection that can be deadly if not treated on time. This is caused by the influenza virus. The common symptoms include fever, chills, muscle aches, cough, fatigue and runny nose.

Flu is a viral infection caused by the Influenza virus. This is a communicable disease. The flu virus attacks the lungs, nose and throat. The respiratory system is weakened. People who have a weak immune system or have a chronic disease are more prone to flu infection.

The most common symptoms include chills, fever, headache, muscle aches, runny nose, cough and fatigue. People generally diagnose flu when they are having respiratory illness which doesn't always supposed to be flu. This misdiagnosis can complicate the situation which makes the treatment of infection difficult.

Flu season is an annually recurring period. The season occurs when its half cold in each hemisphere.

Flu is a communicable disease which lasts for approximately two-three days. During this period, an affected person is advised to stay away from other healthy people which interferes with the business and government work. Also, the residents are not advised to go in public which affects their access to certain resources.

Answer:

Homology

Explanation:

The aspect of the theory of evolution that the drawings support is homology. Homologous organs are organs of different organisms that look similar in structure but perform different functions in reality.

Organs that are built on the same or similar basic plans in the same organisms but perform different functions are thought to have been from the same ancestor. Hence, homology or homologous organ represents one of the evidence used to support the theory of evolution which opines that all living organisms descended with modifications from common ancestors.

Answer:

This question lacks options, the options are;

A) In codominance and incomplete dominance, both of the alleles are dominant.

B) In codominance and incomplete dominance, neither of the alleles are dominant.

C) In codominance, both of the alleles are dominant; in incomplete dominance, neither of the alleles is dominant.

D) In codominance, neither of the alleles is dominant; in incomplete dominance, both of the alleles are dominant.

The answer is C

Explanation:

Codominance and incomplete dominance are both a type of non-mendelian inheritance pattern i.e. patterns of inheritance that do not follow mendelian principles.

- In codominance, the alleles of a gene are both dominant and hence, both express themselves simultaneously for that trait. An example is the alleles A and B of the blood group in humans where both A and B are dominant in the gene.

- In incomplete dominance, neither of the two alleles of gene is dominant and none is recessive either. This means that the two alleles blend together to form an intermediate phenotype in a heterozygous offspring. An example is the pink flower in four o'clock plants resulting from the blending of red and white alleles.

Answer:

The correct answer is b
