How many chromosomes are produced by the first division during meiosis?

notsponge [240]

Answer:

The answer would be Hydrophobic tail and a hydrophilic head. Just some background info, this is located in the cell membrane and the cell membrane is made of up something called the Lipid Bilayer. The word "bi" means 2, so it comprise of 2 layers of phospholipids. These 2 layers of phospholipids are called hyrodrohpbic and hydrophilic. The word "phobic" means fear, so they hydrophobic molecules are NOT attracted to water. Hydrophilic molecules, however, ARE attracted to the molecules.

Hope this helps!

Based on this tree, which statement is correct? A phylogenetic tree of the living organisms. The main branch divides into two br

alexgriva [62]

Answer:

a) Salamanders are a sister group to the group containing lizards, goats, and humans.

Explanation:

A phylogenetic tree is a diagram that represents the evolutive relations between organisms. As you can see in the attached image, the branch that contains salamanders and the group containing lizards, goats and humans, come from the same point as they are in the group 2a and 2b, because of this Salamanders are a sister group to the group containing lizards, goats, and humans.

b) Goats are in the same level as humans because they come from the same point, so they are more close between them than with salamanders.

c) Lizards are more closely related to salamanders than humans, because humans are in an upper branch, then is not true that salamanders are closely related to lizards as to humans.

d) A basal taxon is a lineage that evolved early, so it separates from the tree in an early stage, as it happens to the salamanders that separated early but not humans.

Then the correct answer is a)

Salamanders are a sister group to the group containing lizards, goats, and humans.

The ____________ is the amount of air remaining in the lungs after a forced expiration. The volume of air exchanged during norma

gavmur [86]

The residual air is the amount of air remaining in the lungs after a forced expiration. The volume of air exchanged during normal breathing is called the tidal volume. After a normal inspiration, the amount of air that can then be inspired forcefully is called the inspiratory reserve volume. The total lung capacity minus the residual volume equals the vital capacity. The vital capacity minus the expiratory reserve volume equals the inspiratory capacity. The effects of obstructive disorders, such as asthma or emphysema, may be determined by measuring rapid exhalation with a spirometer.

The lungs are the main organs of the respiratory system. These lungs are also the site of exchange of gases. The air is inspired through the nostrils and this air then reaches the lungs, where the oxygen from air is trapped in the alveoli. This oxygen then diffuses into the bloodstream through capillaries, which is then sent to the heart. From the heart this oxygenated blood travels to different parts of the body. There are several different units of measurement that are used for the measurement of inspired and expired air and their volume.

1. Describe the clamming industry in the 1970 and how it used to be a serious business.

attashe74 [19]

The clamming industry in Long Island used to be very lucrative, raking in as much as $100 Million annually. By the 1970s, it had shrunk to less that $40 million per annum.

<h3>What was to blame for the decline according to the article mentioned above?</h3>

2. According to the New York Times Article of 1985, the reason for the steep decline in the value of the Clamming industry was related to the loss of confidence in the health safety of eating raw shellfish.

3. According to the remarkable discovery of the "208 Study", it was discovered that there was a connection between land use and underground water quality. It was also discovered there was a negative impact of dumping sewers in the ocean on the production of shellfish

4. Some of the solutions that were proposed to manage this situation are:

Using sewers to collect effluents into a septic treatment plant. rather than dumping them into the ocean.
The implementation of secondary sewage treatment supplemented by ocean disposal of the effluents and
Monitoring the salinity levels of the clamp ecosystem.
