Answer:
Chromosomes are the carriers of genetic information. Heredity, in terms of genomics, means the transfer of genetic data/information from parents to offspring.
Explanation:
Biomes are classified based on the type of vegetation, which is dependent on
Explanation:
Terrestrial biomes are distinguished primarily by their predominant vegetation, and are mainly determined by temperature and rainfall. Differences in temperature or precipitation determine the types of plants that grow in a given area . Regions of similar climate and dominant plant types are called biomes.
Climate is the major factor affecting the number and diversity of plants that can grow in a terrestrial biome. Climate determines the average temperature and precipitation, the length of the growing season, and the quality of the soil, including levels of soil nutrients.
The primary factor which determines a biome is the climate. Temperature and precipitation essentially determines what kind of growing season or soil quality the terrain may have,which therefore affects the growth of plants living there.

Explain how a carbon atoms moves From primary consumers to secondary consumers
Explain how a carbon atoms moves From consumers back to the atmosphere (2 different methods)
Explain how a carbon atoms moves From consumers to fossil fuels
Answer:
There are a few types of atoms that can be a part of a plant one day, an animal the next day, and then travel downstream as a part of a river’s water the following day. These atoms can be a part of both living things like plants and animals, as well as non-living things like water, air, and even rocks. The same atoms are recycled over and over in different parts of the Earth. This type of cycle of atoms between living and non-living things is known as a biogeochemical cycle.
All of the atoms that are building blocks of living things are a part of biogeochemical cycles. The most common of these are the carbon and nitrogen cycles.
Tiny atoms of carbon and nitrogen are able to move around the planet through these cycles. For example, an atom of carbon is absorbed from the air into the ocean water where it is used by little floating plankton doing photosynthesis to get the nutrition they need. There is the possibility that this little carbon atom becomes part of the plankton’s skeleton, or a part of the skeleton of the larger animal that eats it, and then part of a sedimentary rock when the living things die and only bones are left behind. Carbon that is a part of rocks and fossil fuels like oil, coal, and natural gas may be held away from the rest of the carbon cycle for a long time. These long-term storage places are called “sinks”. When fossil fuels are burned, carbon that had been underground is sent into the air as carbon dioxide, a greenhouse gas.
Recently, people have been causing these biogeochemical cycles to change. When we cut down forests, make more factories, and drive more cars that burn fossil fuels, the way that carbon and nitrogen move around the Earth changes. These changes add more greenhouse gases in our atmosphere and this causes climate change.
The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle.
Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.
Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.
Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.
Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But since the start of the Industrial Revolution about 150 years ago humans have burned so much fuel and released so much carbon dioxide into the air that global climate has risen over one degree Fahrenheit. The atmosphere has not held this much carbon for at least 420,000 years according to data from ice cores. The recent increase in amounts of greenhouse gases such as carbon dioxide is having a significant impact on the warming of our planet.
Carbon moves through our planet over longer time scales as well. For example, over millions of years weathering of rocks on land can add carbon to surface water which eventually runs off to the ocean. Over long time scales, carbon is removed from seawater when the shells and bones of marine animals and plankton collect on the sea floor. These shells and bones are made of limestone, which contains carbon. When they are deposited on the sea floor, carbon is stored from the rest of the carbon cycle for some amount of time. The amount of limestone deposited in the ocean depends somewhat on the amount of warm, tropical, shallow oceans on the planet because this is where prolific limestone-producing organisms such as corals live. The carbon can be released back to the atmosphere if the limestone melts or is metamorphosed in a subduction zone.

If my starting energy at the producers is 1500 kcal, using the 10% rule, how much energy is available to the tertiary consumers?
Answer:
1.5 kcal
Explanation:
The ten (10) percent rule involves how only as low as 10% of the available energy is transferred to each organism in trophic levels. In an ecosystem, the order of trophic levels are: producer ➡ primary consumer ➡ secondary consumer ➡ tertiary consumer.
According to this question, 1500 kcal of energy is starting at the producer level. Hence;
- 10% of 1500 kcal = 10/100 × 1500 = 150 kcal will be available to the primary consumer
- 10% of 150 kcal = 10/100 × 150 = 15 kcal will be available to the secondary consumer.
- 10% of 15 kcal = 10/100 × 15 = 1.5kcal will be available to the tertiary consumer.
A species of jungle chicken is codominant for red and white feathers. What color would be expressed in the offspring represented by the missing square below if R represents the allele for red feathers and W for white feathers ?
Answer:
i mean i think is white cuz it’s dominate WW
Explanation:
so don’t know
A species of jungle chicken is characterized by its codominance of red and white feathers, so when both the green parents are crossed then, the mission offspring will be white in color, that is, WW, and this is recessive (option c).
What is the significance of the genetic cross and codominance?Codominance is the type of cross in which neither alleles suppresses the other, implying that both are co-dominantly expressed, as in the case of the crossing of the green parents, where there is one RR is the production of the dominant trait that is red. Two will be green; this is the co-dominance, and the other is white, represented by WW.
Hence, a species of jungle chicken is characterized by its codominance of red and white feathers, so when both the green parents are crossed then, the mission offspring will be white in color, that is, WW, and this is recessive (option c).

The Hadley Cell is set up by rising air over the equator. It begins with warming of air surrounding the equator, which
creates a large region of lower surface pressures. This belt of equatorial low pressure causes air to be drawn together
and the warm, moist air over the equator rises upward, to the top of the troposphere. Once the warm air rises, where
does it go?
A)
It circulates back down in the latitudes at the equator
B)
It spreads out north and south and travels toward the poles.
Eliminati
It cools and sinks back down toward Earth at about 300 latitude.
D)
It creates circulation cells in the upper atmosphere that move north and
south across Earth's latitudes.
Once the warm air rises, it cools and sinks back down toward Earth at about 300 latitude. Thus option C is correct.
What is Hadley Cell?Hadley cell is defined as the air rising close to the equator, flowing poleward at a height of 10 to 15 kilometers above the earth's surface, falling in the subtropics, and then returning equatorward close to the surface.
It can also be defined as the low-latitude overturning circulations, where air rises at the equator and sinks at a latitude of around 30 degrees.
The tropical easterlies and trade winds are produced by the Hadley cell, a large-scale atmospheric circulation pattern in the tropics, which is brought on by warm air rising in the tropics, flowing toward the poles, then cooling off, falling, and flowing back toward the equator.
Thus once the warm air rises, it cools and sinks back down toward Earth at about 300 latitude. Thus option C is correct.

Answer:When we stand up from sitting or lying down, our blood vessels respond to gravity by narrowing to prevent our blood pressure falling. This ensures a steady supply of oxygenated blood to the brain.
Orthostatic hypotension is a form of low blood pressure. It happens when the blood vessels do not constrict (tighten) as you stand up. It is usually a symptom of an underlying disorder rather than a disease in itself. The condition is also known as postural hypotension.
Everyone is likely to experience a mild form of postural hypotension at some time. It’s the lightheaded feeling you may get if you leap out of bed very quickly.
Orthostatic hypotension — also called postural hypotension — is a form of low blood pressure that happens when you stand up from sitting or lying down. Orthostatic hypotension can make you feel dizzy or lightheaded, and maybe even cause you to faint.
Orthostatic hypotension may be mild, and episodes can last for less than a few minutes. However, long-lasting orthostatic hypotension can signal more-serious problems, so it's important to see a doctor if you frequently feel lightheaded when standing up.
Occasional (acute) orthostatic hypotension is usually caused by something obvious, such as dehydration or lengthy bed rest, and is easily treated. Chronic orthostatic hypotension is usually a sign of another health problem, so treatment varies.
Dizziness is a word that is often used to describe two different feelings. It is important to know exactly what you mean when you say "I feel dizzy," because it can help you and your doctor narrow down the list of possible problems.
Lightheadedness is a feeling that you are about to faint or "pass out." Although you may feel dizzy, you do not feel as though you or your surroundings are moving. Lightheadedness often goes away or improves when you lie down. If lightheadedness gets worse, it can lead to a feeling of almost fainting or a fainting spell (syncope). You may sometimes feel nauseated or vomit when you are lightheaded.
Vertigo is a feeling that you or your surroundings are moving when there is no actual movement. You may feel as though you are off balance, spinning, whirling, falling, or tilting. When you have severe vertigo, you may feel very nauseated or vomit. You may have trouble walking or standing, and you may lose your balance and fall.
Although dizziness can occur in people of any age, it is more common among older adults. A fear of dizziness can cause older adults to limit their physical and social activities. Dizziness can also lead to falls and other injuries.
Lightheadedness
It is common to feel lightheaded from time to time. Brief episodes of lightheadedness are not usually the result of a serious problem. Lightheadedness often is caused by a momentary drop in blood pressure and blood flow to your head that occurs when you get up too quickly from a seated or lying position (orthostatic hypotension). Ongoing lightheadedness may mean you have a more serious problem that needs to be evaluated.
