Answer 2

Answer :

Incubation is 18 days from the time cockatiels sit in earnest, therefore, count a few extra days if sitting is delayed. Allow the female to abandon the eggs of her own accord rather than removing them even if incubation time is over, because your cockatiel will only lay additional eggs if she reacts to their absence.

Under which conditions would air hold less water vapor than it holds at 30°C
(86°F) with sunny skies?
A. 34°C (94°F) with cloudy skies
B. 30°C (86°F) with cloudy skies
C. 22°C (86°F) with sunny skies
D. 32°C (90°F) with sunny skies

Answers

Answer:

B

Explanation:

jus CS its right

The relative humidity of the air affects how much water vapor it can hold. 30°C (86°F) with cloudy skies would air hold less water vapor than it holds at 30°C (86°F) with sunny skies. So, the correct option is B.

What is Relative humidity?

Relative humidity (RH) measures the amount of moisture in the air compared to the maximum amount of moisture in the air at a given temperature and pressure. It is a standard figure for describing the moisture content of the air and is expressed as a percentage.

At a given temperature and pressure, air is considered to have 100% relative humidity when it contains all the moisture it can hold. The temperature at which the moisture in the air begins to condense into droplets is known as the dew point.

Therefore, the correct option is B.

Which mechanism allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries

Answers

Answer:

Diffusion.

Explanation:

The mechanism that allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries is simple diffusion.

Simple diffusion is a passive transport mechanism that allows lipid-soluble substances to move across the membranes of endothelial cells in capillaries. This process occurs down a concentration gradient, from an area of higher concentration to an area of lower concentration, without the need for energy expenditure.

The membranes of endothelial cells, which make up the walls of capillaries, are composed of a lipid bilayer. Lipid-soluble substances, such as oxygen, carbon dioxide, steroid hormones, and certain lipid-soluble drugs, can readily diffuse through this lipid bilayer due to their ability to dissolve in and pass through the hydrophobic interior of the membrane.

Unlike lipid-soluble substances, water-soluble substances, such as ions and polar molecules, are unable to passively diffuse through the lipid bilayer. Instead, they rely on specific transport mechanisms such as facilitated diffusion or active transport to cross the endothelial cell membrane.

In the context of capillaries, simple diffusion allows lipid-soluble substances to move from the bloodstream through the endothelial cell membranes and into surrounding tissues or vice versa. This process plays a crucial role in the exchange of gases, nutrients, and waste products between the bloodstream and the tissues.

It is important to note that while simple diffusion allows for the passage of lipid-soluble substances, the movement of these substances can also be influenced by factors such as concentration gradients, molecular size, solubility, and the presence of transport proteins. However, the primary mechanism by which lipid-soluble substances traverse the endothelial cell membranes of capillaries is through simple diffusion.

what is the cell wall function and factory part or worker?

Answers

Answer:

Major cell parts function just like the structures and people who work together in a factory. Cells have strong cell walls and a cytoskeleton to keep their shape; the walls are made of fiber for protection just like a factory building has sturdy walls for support.

The cell wall serves as a protective and structural layer surrounding plant, fungal, and bacterial cells. It provides rigidity, support, and defense against external pressures and pathogens.

In various species, the cell wall serves as a robust outer layer. Its primary component in plants is cellulose, which helps to preserve cell structure, limit excessive water absorption, and promote growth. Chitin is found in the cell wall of fungi, providing both structural integrity and protection.

Bacteria have a variety of cell wall compositions; peptidoglycan, for example, is an essential part of many bacterial cell walls. Along with other cellular components, this "factory-like" part of the cell performs its functions. It is comparable to a factory's base, supporting the cell's framework, and worker, guarding against threats and preserving the cell's overall operation.

Answers

The desert that occurs in North America is the Great Basin Desert and it is located at Nevada of North America.

CAM pathway, which is also called Crassulacean Acid Metabolism, is a pathway that involves carbon fixation that occurs in plants growing in arid areas.

With this pathway these plants are able to photosynthesize during the day, but only exchange gases at night.

An arid habitat is an environment that is characterized by extreme lack of water, example is the desert.

In North America, the desert that occurs there is the Great Basin Desert. It spreads into different states which include:

Explain how homologous structures are used as a source of evidence to infer evolutionary relationships between modern and fossil organisms

Answers

Answer:

Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.

Explanation:

Analogous structures demonstrate that identical selective pressures might result in similar adaptations, whereas homologous structures indicate evidence for shared ancestry.

What are analogous structures?

In contrast to homologous structures, analogous structures are characteristics of different species that have evolved in response to a similar environmental challenge and are similar in function but not necessarily in structure.

While comparable structures demonstrate that similar selective pressures can result in similar adaptations, homologous structures suggest that they have a common ancestor (beneficial features).

Therefore, homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.

Which of these changes is a possible negative consequence of farmers
allowing livestock to overgraze a pasture?
O A. Desertification
O B. Shortage of freshwater
O c. Deforestation
O D. Abundance of clean air

Answers

Given what we know, one of the possible negative consequences of farmers  allowing livestock to overgraze a pasture is desertification.

What is Desertification?In simple terms, desertification is when the land becomes so dry and void of life that it can be considered a desert. This can be caused by many factors, primarily the lack of vegetation.

How can overgrazing lead to Desertification?Overgrazing can lead to desertification due to the fact that the plants and vegetation are not given the opportunity to regrow.The presence of vegetation allows the soil to remain moist and fertile by moving minerals and water through it. Overgrazing causes a lack of vegetation which creates dry and infertile land, which leads to complete desertification.

Therefore, we can confirm that one of the possible negative consequences of farmers  allowing livestock to overgraze a pasture is desertification due to the damage caused to the soil in the absence of vegetation.
