A. These signals have been calibrated against actual visual and location readings for the amount of rain falling and cloud water content. ... Thus the computer generates a visual image according to the reflectivity of the amount of water in colors on a map.

B. Reflectivity of an object helps indicate the amount of water that a cloud may carry. The stronger the reflected signal from the radar signal sent out, the easier the meteorologist will be able to tell what to expect. ... This in turn is interpreted by the meteorologist from past experience as what to expect in the future.

The organisms living in an aquatic environment have to undergo osmoregulation and survive in a hypotonic environment. The organisms such as paramecium, protists, and unicellular algae have contractile vacuoles.

The functions of the contractile vacuoles include:

1. Contractile vacuoles help in the osmoregulation, such that the movement of solute particles inside and outside of the cells.

2. The contractile vacuoles are also required to remove excess water from the organisms.

3. The vacuoles contract to discharge the fluid for the survival of organisms like paramecium and algae.

Thus, the contractile vacuoles contract to allow the organisms to survive in a hypotonic environment.

The phase of swallowing that was most likely involved in the accidental swallowing of her gum is the pharyngeal phase.

There are different phases of swallowing is divided into three, namely:

The oral phase is voluntary while the pharyngeal and the esophageal phase is involuntary.

The pharyngeal phase involves the movement of the bolus of food from the oropharynx into the esophagus.

Since the Joanna accidentally swallowed her gum, it is an involuntary action of the pharyngeal phase of swallowing.

If the carrying capacity for the North Atlantic cod on the newfound land is 500,000 tons, then we would expect that when there are 250,000 tons of cod on the grand banks, the population growth will be greatest.

The carrying capacity speaks volumes about the maximum amount of a species population that the ecosystem can sustain permanently provided there is the availability of water, food, habitat, and other life essentials.

In terms of population ecology, it is defined as the maximum burden that the environment can tolerate.

In population ecology, populations normally decrease above the carrying capacity while they increase below the carrying capacity. A decline in population size above the carrying capacity can be caused by a variety of factors, such as a lack of sunshine, space, or food availability.

Therefore, we can conclude that If the carrying capacity for the North Atlantic cod on the newfound land is 500,000 tons, the rate of population increase will be maximum and greatest when there are 250,000 tons of cod on the Grand Banks.

The movement of water across cellular membranes through aquaporins is known as osmosis. Water moves down the concentration gradient. The fourth option is the correct answer.

Molecules can pass the cell membrane both actively and passively. In passive transport, no energy or ATP is required. Molecules can move from a higher concentration to a lower concentration.

Diffusion and osmosis are examples of passive transports. In diffusion, gases and other small molecules pass the cell membrane from a higher to a lower concentration. Water is a polar molecule, so it doesn't pass the membrane due to its nonpolar nature. Cells have aquaporin channels that are made for water.

Through aquaporins, water passes into the cell. This is called osmosis. In active transport, energy is required. When a molecule passes from a lower concentration to a higher concentration, energy is needed. An example is sodium-potassium ATPase.

Hence, the correct answer is osmosis. The fourth option is the correct answer.

All of our energy and nutrition come by way of the gastrointestinal (GI) tract. It is an amazing machine well designed for digesting and absorbing nutrients and for shielding the rest of the body from microorganisms, viruses and other foreign matter. The GI tract spans from the mouth to the anus, with each separate organ having a role in digestion, absorption or excretion.Lastly, if you would like to learn more about yourself and how you can best reach your own nutritional and fitness goals, we encourage you to take a look at the following home health testing guides and resources:

Technically Mitosis and Meiosis

Explanation:

Mitosis is the spliting of Body Cells. Mitosis goes through 4 phases that are easy to remember as PMAT. Mitosis starts with Interphase then moves to Prophase, Metaphase, Anaphase, and Telephase. These steps also occur in Meiosis. However Meiosis goes through these step twice. If you need further explaination of mitosis and meiosis I recomend the amoeba sisters.

Glands that have branched ducts and secretory cells that form sacs at one end of the ducts are called compound alveolar glands.

The exocrine gland secretes enzymes outside the gland through the duct. The gland can be unicellular, multicellular, compound, tubular, alveolar, etc. Their modes of functions vary too. An example of an alveolar gland is the mammary gland. Sweet glands are an example of tubular glands.

Hence, glands having branched ducts and sac-like secretory cells are called compound alveolar glands.

The hormone that directly opposes the actions of natriuretic hormones is aldosterone.

Aldosterone is a hormone produced by the adrenal glands, specifically the adrenal cortex. It acts on the kidneys to promote the reabsorption of sodium ions and the excretion of potassium ions.

Natriuretic hormones, on the other hand, promote the excretion of sodium ions and the reabsorption of potassium ions in the kidneys, leading to increased urine production and decreased blood volume.

Therefore, aldosterone counteracts the effects of natriuretic hormones by increasing sodium reabsorption and reducing potassium excretion, which helps to retain water and maintain blood pressure.

In summary, while natriuretic hormones promote sodium excretion and water loss, aldosterone works in the opposite direction by promoting sodium reabsorption and water retention.

Answer:

An algal bloom.

Explanation:

The input of sewage, fertilizer runoff, and animal waste can cause the formation of an algal bloom (abundances of cyanobacteria)  because of the excess nutrients (nitrogen or phosphorus). If there are too much nutrients in the water (caused by the sewage, fertilizer runoff, and animal waste) it creates a perfect environment for excess growth, being an algal bloom. Algal blooms are toxic and are known to be harmful to the animals that rely on this source for their survival and humans as well.

Given what we know about global carbon levels in the present and the past, we can confirm that in order to be at the level of early civilizations, the modern-day carbon level should be at 280 parts per million.

Global atmospheric carbon levels are measured in parts per million. What this means is that for every one million units of mass in the atmosphere, 280 of them were carbon. This means that in recent years, the global carbon levels in the atmosphere have doubled.

The primary cause of these increased carbon levels is industrial pollution. Chemicals are released into the atmosphere as a by-product of industrial processess. This began with a noticeable spike during the industrial revolution and has then increased without end.
