What type of cells surround the stomata

What is meant by suggesting that Earth's oceans are connected?

Katen [24]

C seems like the answer because at the end of South America, there's nothing blocking the two oceans there from connecting. All of the oceans are connected together. They're just different because of where they are and the conditions of that area of earth.

I dont' think water flows under the continents either so D doesn't sound right at all. A is just beyond logical because there's no way that has anything to do with how the oceans are connected to each other. B MAY be the answer but I'm leaning more towards C.

I digest waste and recycle old cell parts.What type of cell organelle am I?

klasskru [66]

You are a Lysosome!

Lysosomes:
<span>- Common in animal cells.
- Helps cell digest proteins.
- Cleanup crew of the cell.
- Contain powerful chemicals that digest nutrient molecules in the cell.
- When other organelles stop working, the lysosomes break down and recycle the old cell parts so they can be used again.
- The chemicals in the lysosomes only break down unhealthy cell parts. - ------ Membrane surrounds the lysosomes to stop them from destroying the rest of the cell
</span>
Hope I helped! :)

A 22-year-old man was in a motorcycle accident with resultant neck injuries that led to partial paralysis of the upper and lower

Arte-miy333 [17]

Answer:

We are given:

Minute Ventilation, MV = 6L/min

Respiratory Rate, RR = 30 b/min

PaO2 = 61mmHg

PaCO2 = 47mmHg

a) to find Tidal Volume, TV, we use:

TV = MV/RR

TV = 6/30

= 0.2litres => 200ml

For Alveolar ventilation, AV, we have:

AV = (Tidal Volume-dead space)×RR

AV = (200 - 150)×30

AV = 1500ml/min

The normal dead space value is 150ml.

Comparing both TV and AV with the normal values, it can be said that, since he has a TV of 200ml, he is defficient because a normal TV level is 500ml.

The man has an AV of 1500ml/min, which is low when compared to the normal AV value which is 4200ml/min.

2) The factor contributing to the deceased alveolar ventilation is the increase in PaCO2, in this case, the PaCO2 is 47mmHg, whereas the normal PaCO2 level is between 38-42mmHg

3) The muscle involved in this problem is the lower rib cage and thoracic cavity, while the nerve involved in this problem is the spinal cord.

4) The residual volume is decreased

5) Dyspenea simply means shortness of breath. It happens when a person experiences difficulty in breathing.

6) The cause of Dyspenea could be that the tidal Volume is lowered by the reduced diaphragmatic and intercoastal innervation or it could also be caused by chest trauma

7) The reflexes that causes tachypnea in this individual are the central and peripheral chemoreceptors. A individual has a PaO2 of 61mmHg and this low PaO2 causes the high breathing rate becauses peripheral chemoreceptors senses it and the medulla sends the signal out

Classify each of the following as homozygous dominant, heterozygous, or homozygous recessive.

mario62 [17]

First, we will elaborate the terms that are being used.

Heterozygous:
This means that the organism has a set of alleles which are different from one another. One copy may be for the dominant trait and the other for the recessive one.

Homozygous:
The organism has two copies of the same allele

Dominant:
An allele that will express itself even if only one copy of it is present. These are usually represented by capital letters.

Recessive:
An allele that requires both copies to be expressed. These are usually represented by lower-case letters.

A: Heterozygous

B: homozygous recessive

C: Homozygous dominant

D: Homozygous recessive

E: Homozygous dominant
