Why do different types of cells have different structures/ shapes
Answer:
Cells have different shapes because they do different things. The shapes of cells have evolved to help them carry out their specific function in the body, so looking at a cell's shape can give clues about what it does. Neurons are cells in the brain and nervous system.

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.

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).

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.

how does mRNA get out of the nucleus
Answer: mRNA moves through pores in the nuclear membrane
Explanation: nuclear membrane pores permit the passage of mRNA, but only after processing within the nucleus. The non-coding parts of the RNA are deleted (introns), the 5’ end capped to prevent premature degradation, and a string of A nucleotides added at the 3’ end (improves stability).

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.

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.
