Answer:

They are smaller than blood capillaries.

Explanation:

Lymphatic capillaries drains the extracellular fluid present between the cell spaces. The fluid is known as lymph as it enters the lymph capillaries. These capillaires drains into lymph vessels that drains to lymph nodes and lymph ultimately enters the venous circulation.

Lymphatic capillaries are slightly larger than blood vessels and these capillaries have close ends. The walls of lymph capillaries are made up of endothelial cells. The endothelial cells overlap in lymph vessels and when the pressure in ECF is greater these cells move and create a sort of gap for the movement of ECF inside the lymph capillary but when the pressure inside the capillary is greater these cells again overlap and does not allow the lymph to move outside of capillary. Thus lymph capillaries only allow the ECF to enter the capillary but does not allow the lymph to go out from capillary. Lymph capillaries have greater internal pressure than blood vessels.

During which process is ethanol produced?

Kipish [7]

Answer:

Alcohol fermentation

Explanation:

When oxygen availability is low, the cell can't perform aerobic respiration to breakdown glucose. Instead, anaerobic respiration must be performed. This occurs in cells which consume large amounts of energy, such as muscle cells. Anaerobic respiration produces much less energy than aerobic respiration

One type of anaerobic respiration formed by yeast is called alcohol fermentation (also called ethanol fermentation). This begins with glycolysis, where one molecule of glucose is broke down into 2 molecules of pyruvate. The energy from this reaction generates 2 molecules of ATP, and converts NAD+ to NADH.

Then, the two molecules of pyruvate are further broke down into 2 acetaldehydes (releasing two molecules of carbon dioxide as a by-product). These two molecules of acetaldehyde are then converted into tw molecules of ethanol, using the H ions from NADH, converting it back to NAD+. See the attached picture

This process is taken advantage of to brew beer and wine.

Answer:

The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.

Explanation:

During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

1. What strengths and weaknesses of the systems approach and the use of models have been

saveliy_v [14]

Answer and Explanation:

Today, the average proportion of fish production at a global scale used for human consumption is over 75 %. This has led to several disadvantages, such as overexploitation of fish and seafood, but to other advantages, such as aquaculture and economic improvement.

<em>Weaknesses</em>:

Overfishing / overexploitation that leads to the significant decline of marine organisms.
Noise pollution caused by fishing ships
Waste and other pollutants that also increase marine contamination.
An average person currently consumes almost twice as much seafood as half a century ago.

<em>Strengths</em>:

The implementation of aquaculture.
Higher economic gains
More opportunities / jobs

If a spinach plant with flat (FF) green (GG) leaves is crossed (pollination and fertilization occur) with another spinach plant

never [62]

Answer:

The offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, the offsprings will only inherit the flat, green traits.

Explanation:

This question involves two different genes coding for leaf shape and leaf color respectively. The alleles for flat (F) and green (G) leaves are dominant over the alleles for crinkly (f) and purple (g) leaves.

According to this question, If a spinach plant with flat (FF) green (GG) leaves is crossed with another spinach plant with crinkly (ff) purple (gg) leaves, all the offsprings in the F1 generation will possess a FfGg heterozygous genotype.

This genotype means that the F1 offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, they will only inherit the flat, green traits because they are dominant over the crinkly and purple trait.
