Answer: C. Stomata would not open and close.
Explanation: The main function of guard cells is to regulate the opening and closing of the pore formed between the gap of two guard cells, termed as stomata. Option A is incorrect as stomata are the least susceptible area from where pathogens can enter the plant cell. Option B is incorrect because photosynthesis is not directly and much affected by guard cells. Option D is incorrect as chloroplasts are not associated with the guard cells. Stomata are directly linked with movement of guard cells, so correct answer is option C. Through stomata, exchange of gases and water vapor takes place.

Differential white blood cell count data table answers
A Differential White Blood Cell Count is a medical test that measures the number of different types of white blood cells in a blood sample. These types include neutrophils, lymphocytes, monocytes, eosinophils, and basophils, and their distributions can help indicate different health conditions.
Explanation:A Differential White Blood Cell Count is a medical procedure that differentiates between the types of white blood cells in a patient's blood. The cells differentiated include neutrophils, lymphocytes, monocytes, eosinophils, and basophils. The frequency of these cell types is usually expressed as a percentage of the total white blood cell count. For instance, a normal differential count could present as follows: neutrophils 50%-70%, lymphocytes 20%-40%, monocytes 2%-8%, eosinophils 1%-4%, and basophils 0.5%-1%.
Increased or decreased levels of the different types of white blood cells in a differential count can indicate various health issues. For example, a high neutrophil count could suggest a bacterial infection, while a high lymphocyte count might indicate a viral infection.

A differential white blood cell count measures the amount and types of leukocytes in the peripheral blood, with different ranges for different species. These cells, comprising granulocytes and agranulocytes, play a central role in the immune system. Fluctuations in their count can offer clues about ongoing infections or medical conditions.
Explanation:The differential white blood cell count is a test that measures the amount of different types of white blood cells, or leukocytes, found in your blood. Leukocytes are the predominant white blood cells in the peripheral blood and their count varies among different species. For instance, primate counts range from 4,800 to 10,800 cells per µl, dogs from 5,600 to 19,200 cells per ul, cats from 8,000 to 25,000 cells per µl, cattle from 4,000 to 12,000 cells per µl, and pigs from 11,000 to 22,000 cells per ul.
Leukocytes are important as they are a crucial part of the immune system. Different types of leukocytes are identified by their appearance after histologic staining. The granulocytes include neutrophils, eosinophils, and basophils, and the agranulocytes include monocytes and lymphocytes.
Changes in the count of these cells can indicate an ongoing infection or a medical condition. For instance, an elevation in white blood cell count, like in Olivia's case, where the count increased to 28.5 K/µL from a normal range of 6.0–17.5 K/µL, indicates a strong immune response to an infection.

Which vessels allow diffusion of oxygen and nutrients across their cell layers?
Answer:
Capilleries
Explanation:
Capillaries are the places where the exchange of substances between blood and surrounding tissues occurs. Substance exchange can occur between and through the cells that make up the vessel wall. The pores present in some types of blood capillaries also act as transfer sites. It is noteworthy that the permeability of these vessels varies from one body region to another. In summary, we can say that it is the capillaries that allow the diffusion of oxygen and nutrients through their cell layers.
Blood capillaries are vessels of the cardiovascular system that are characterized by their small caliber.

From the capillaries of the abdominal organs and hind limbs, blood flows to the _____. from the capillaries of the abdominal organs and hind limbs, blood flows to the _____. right atrium left atrium aorta capillaries of the lungs inferior vena cava
Blood from the capillaries of the abdominal organs and hind limbs flows into the inferior vena cava. From there, the blood flows into the right atrium and then is pumped into the right ventricle, continuing the blood circulation process.
Explanation:The question asks where the blood flows from the capillaries of the abdominal organs and hind limbs. The blood in this case flows to the inferior vena cava.
The capillaries unite to form venules, which merge into ever-larger veins, eventually flowing into the two main systemic veins, the superior vena cava and the inferior vena cava. The inferior vena cava receives blood from veins beneath the diaphragm, including from the abdominal organs and hind limbs.
The blood in the superior and inferior venae cavae flows into the right atrium, where it is pumped to the right ventricle, continuing the process of blood circulation as long as the individual is alive.

X chromosome will be contained by the sex cells of a female giraffe and Homozygous dominant for a widow's peak. So, the correct options for 1 and 2 are (A) and (A) respectively.
What is X chromosome?X chromosome is defined as one of the two sex chromosomes in humans while the other chromosome is the Y chromosome. Sex chromosomes make up one of the 23 pairs of human chromosomes in each cell where the X chromosome spans about 155 million DNA building blocks that are base pairs and represents about 5 percent of the total DNA in cells.
A female giraffe, like many mammals, exhibits dimorphism in female chromosomes, meaning females have XX chromosomes while males have XY chromosomes, unlike other organisms such as birds. A sex cell of an organism is also called a gamete, or a cell that is formed through meiosis or reductional division.
Gametes are haploid which only contain one set of chromosomes. Thus, a female giraffe will produce all gametes containing an X chromosome. While the child having widow's peak is homozygous dominant.
Thus, X chromosome will be contained by the sex cells of a female giraffe and Homozygous dominant for a widow's peak. So, the correct options for 1 and 2 are (A) and (A) respectively.

when weather conditions are disrupted by El Nino how does this affect ocean nutrients
Answer:
Oceans upwelling decreases, reducing levels of nutrient-rich water
Explanation:
Typically, trade winds blow from east to west in the Pacific pushing warm surface ocean waters towards Asia. This causes upwelling of cold ocean currents from the depths of the oceans on the west coast of South America bringing up nutrients from the depths.
During Elnino, however, these trade winds weaken, and predominant winds blow eastwards, reducing this upwelling of colder deeper waters.
When weather conditions are disrupted by El Nino then Oceans upwelling decreases and levels of nutrient-rich water is reduced.
Further Explanation:
The Pacific Ocean is the Earth's largest and deepest Oceanic division that stretches from Arctic Ocean towards North to Southern Ocean towards South. It is also bounded Australia and Asia in the Western side and America on the eastern side. It covers consists of the Earth's 46% total surface water. The imaginary line Equator that splits the Earth Into two hemispheres passes through it centrally and divides the Earth into the Southern hemisphere and Northern Hemisphere.
Warm current in the Pacific Ocean is caused due to change in the temperature of the water that is called El Nino. It is related to the belt of warm ocean water developed in the central and eastern-central equatorial Pacific that includes the area of South America's Pacific coast. El Nino is conveyed by western Pacific high air pressure and eastern Pacific low air pressure. The countries that are under the developing stage get most affected by it, particularly those countries that depend on fishing and agriculture.

Which part of a plant absorbs most of the water and minerals taken up from the soil? question 8 options:
a.the thick parts of the roots near the base of the stem
b.storage roots
c.root cap
d.sections of the root that have secondary xylem
e.root hairs?
The correct answer is root hairs. Root hairs are extensions of fibrous or tap roots and they are adapted to absorption of water and nutrients from soil. They are long and thin which makes them able to penetrate soil particles so that they can obtain nutrients and moisture. They also have increased surface area which accelerates the absorption process.
Answer:
e. root hairs
Explanation:
The uptake of water and mineral salts in plants occurs mostly at the root epidermis level, especially through root hair. These structures are extensions of epidermal cells that increase the surface area of contact with the ground, and consequently the absorption capacity.
These root hairs are microscopic and are actually extensions of the root epidermis cells. The presence of these hairs makes the root area available for the absorption of these resources to be much larger.
