However, lions have 38 chromosomes (19 pairs) and there cubs get their chromosomes from there parents; with each parent donating 19 each. They also have a pair of chromosomes known as sex chromosomes (X and Y). The female always donates the X chromosome and the male donates either a X (which leads to a female cub) or a Y (which leads to a male cub), just like in many mammals.
NOTE: Chromosomes are threadlike structures in the nucleus of a cell that carry/stores genetic materials/genes.

Why does a compressed air can become extremly cold when you use it?
Answer:
The reason the compressed air gets cold after being used is due to a process known as adiabatic cooling, a property of thermodynamics. A gas, initially at high pressure, cools significantly when that pressure is released. The compression needed to turn a gas to liquid allows a large amount of gas to fit in a relatively small space, and when that gas is released to a large space, it rapidly expands to fill the space.

b
clear skies
c
sunny days
d

clouds
Answer:
F
Explanation:
Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies with large diurnal temperature changes due to greater radiation at night and greater sunshine during the day.

How does the ozone layer help maintain ground-level air equality?
Answer:
The ozone layer absorbs a large portion of incoming UV radiation, which keeps ground-level ozone from forming. A higher percentage of UV radiation entering the troposphere would allow a greater amount of ozone to form in the troposphere. Ozone is a pollutant in the troposphere. By regulating the amount of UV radiation that enters the troposphere, the ozone layer also regulates the amount of ozone formation in the troposphere.
Explanation:
edg 2020
The ozone layer absorbs a large portion of incoming UV radiation, which keeps ground-level ozone from forming.
What is ozone layer?The amount of ozone that forms in the troposphere would increase if more UV radiation entered the atmosphere. Pollutants in the troposphere include ozone.
The ozone layer controls the quantity of ozone formation in the troposphere by controlling the amount of UV radiation that reaches it.
Nearly all of the sun's harmful UV light is absorbed by a thin layer of air called the ozone layer in the Earth's atmosphere. "Ozone holes" are terms used frequently to describe regions where the ozone layer is degrading.
Therefore, The ozone layer absorbs a large portion of incoming UV radiation, which keeps ground-level ozone from forming.

What is the difference between aerobic and anaerobic cellular respiration?
Answer: Explanation:
Aerobic respiration is a set of metabolic reactions that take place in the presence of oxygen, occurring in a cell to convert chemical energy into ATPs. Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives.
The main difference between aerobic and anaerobic respiration is that the former takes place in the presence of oxygen while the other is in the absence of oxygen.
Aerobic respiration refers to respiration in the presence of oxygen according to the following equation:
[tex]C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O + 32 ATP[/tex]
While anaerobic respiration refers to respiration in the absence of oxygen according to the following equations:
[tex]C_6H12O6 ---> 2CO_2 + 2C_2H_6O + 2ATP[/tex]
Thus, another difference is that aerobic respiration generates more energy (32 ATP) than anaerobic respiration (2 ATP).

help plzzz 2 more will mark brainlest. Changes to abiotic factors in an environment can impact biotic factors. Climate change may be reducing the amount of ice floating on the world’s oceans. How can this change MOST likely alter the food supply available to marine consumer organisms?
Answer: Here are three reasons if they don't help just tell me.
1. Changes in water temperature can affect the environments where fish, shellfish, and other marine species live. As climate change causes the oceans to become warmer year-round, populations of some species may adapt by shifting toward cooler areas. Oceans are becoming more acidic. 2. Oceans are becoming more acidic. The acidity of seawater is increasing as a direct result of increasing carbon dioxide levels in the air from human activities, like burning fossil fuels. Concentrations of carbon dioxide are higher than in the last 800,000 years. Carbon dioxide dissolves in water, changing seawater chemistry and decreasing pH (making seawater more acidic). The ocean’s increased acidity results in thinner shells and more shellfish die as they become easier for predators to eat. 3. More severe storms and precipitation can pollute coastal waters. Warmer oceans increase the amount of water that evaporates into the air. When more moisture-laden air moves over land or converges into a storm system, it can produce more intense precipitation—for example, heavier rainstorms. Heavy rain in coastal areas can lead to increases in runoff and flooding, impairing water quality as pollutants on land wash into water bodies. Some coastal areas, such as the Gulf of Mexico and the Chesapeake Bay, are already experiencing “dead zones” – areas where water is depleted of oxygen because of pollution from agricultural fertilizers, delivered by runoff. The phrase “dead zone” comes from the lack of life – including fish – in these waters.

Construct an Explanation Is the importance of an element in the body related to its percentage of body weight? Cite the evidence in the table to support your explanation.
Answer:
The osmosis processes are spontaneous processes in our body, these processes have a high enthalpy, tend to disorder, and it is necessary if or if a permeable or semi-permeable membrane to water between two spaces with different concentrations of solutes.
Explanation:
The osmosis processes occur spontaneously, this means that their onset in the process is natural, an example of this is the edema of the lower limb on hot days, or in inflammatory situations, or the example that was cited with the chicken's egg.
The water that passes through the permeable membrane will always go from the zone with the lowest concentration to the one with the highest concentration, in order to equalize and equalize the concentrations and molarities of the compartments that interact with each other.

Need Help!! Read the article “Tweaking How Plants Manage a Crisis Boosts Photosynthesis,” and then answer the following questions.
Part A
How might the research described in the article help address the food supply for a growing population?
in the article Tweaking How Plants Manage a Crisis Boosts Photosynthesis he reports that it is the first example in which crop growth was improved by improving photosynthesis, thus making plants more resistant and more productive in difficult climatic times.
How to explain photosynthesis?Photosynthesis is a process carried out by plants to produce the energy necessary for their survival. As it happens? Water and mineral salts are removed from the soil through the root of the plant and reach the leaves through the stem in the form of sap, called raw sap.
What are the processes of photosynthesis?Photosynthesis is divided into two basic processes: light reaction and carbon fixation reaction. In the first reaction, two photosystems are involved, which are units formed by pigment molecules. In these photosystems, two regions are observed: the antenna complex and the reaction center.
