How many hydrogen atoms are present in each water molecule?

You leamed that carbon is an important building block of organisms and that moves through organisms, between organisms, and the

Natasha2012 [34]

Answer:

1. Atmosphere and ecosystem

2. Carbon/CO2 is absorbed by the plants and then released as oxygen.

3. Carbon is used in the cellular respiration process to make ATP.

4. Decomposers break down dead material and release CO2 in that process into the atmosphere for plants to use that carbon for photosynthesis again.

Because lymph vessels are very low-pressure conduits, movements of adjacent tissues are important in propelling lymph through th

Fudgin [204]

Answer:

True.

Explanation:

Lymphatic system is one of the most important system of the body that carries the lymph fluid towards the heart. This system plays an important role in the body immune system.

The pressure in the lymph vessels are very low. The movement of adjacent tissue in the lymph is important to propel it through the lymphatics. The intrinsic or extrinsic compression are important for the lymph flow.

Thus, the correct answer is True.

1. In which way does the circulatory system rely on the skeletal system? (1 point)

german

Answer:

The correct option is Blood cells are produced in bone marrow.

Explanation:

Skeletal system can be described as the system which comprises of all the bones and joints of an organism. The main function of the skeleton system is to provide support and protection to the organism.

The circulatory system can be described as a system which comprises of the heart, blood vessels and blood. This system is mainly involved in the transportation of substances like oxygen, nutrients etc in the body.

The skeletal system interacts with many other systems of the body and helps them perform their functions. For example, the skeletal system interacts with the muscular system so that a muscle can contract and relax.

The skeletal system interacts with the circulatory system by producing blood cells in the bone marrow. Red blood cells, as well as white blood cells, are produced by this process.

In beetles, the gene for color and the gene for pattern are located on the same chromosome and exhibit recombination. The lined

Pie

Explanation:

The genes that determine color and pattern are linked.

Solid pattern allele (L) is dominant over lined pattern (l)
Blue color allele (B) is dominant over aqua color (b)

<h3>Initial cross</h3>

Homozygous lined aqua beetle has the genotype lb/lb

It can produce only 1 type of gamete: lb

X

Homozygous solid blue beetle has the genotype LB/LB

It can produce only 1 type of gamete: LB

The F1 is formed by the union of the parents' gametes, so it will have the genotype lb/LB

<h3>F1 test cross</h3>

Test crosses involve a homozygous recessive individual.

The homozygous recessive individual lb/lb can only produce 1 type of gamete:

lb

The F1 individual lb/LB can produce 4 types of gametes:

lb - parental
LB - parental
lB - recombinant
Lb - recombinant
