NASA can research the typical climate condictions in the world. The structure of pinecones and what they are made of can be classified depending on the type of tree it came from. For example, moss and fungus that is found on the structure of the pinecone can be tested and can help ensure successful reproduction of the certain species. Finally, it can be reproduced depending on the environment the tree was raised in.

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.
Explain how body cells (somatic) and sex cells (gametes) are made up from chromosomes?
ﾟ+*:ꔫ:*﹤ ﹥*:ꔫ:*+ﾟAnswer:ﾟ+*:ꔫ:*﹤ ﹥*:ꔫ:*+ﾟ
Somatic cells are produced through the cell division process of mitosis. ... Cells with two copies of each chromosome are called diploid. Sperm and egg cells, called gametes, are formed through meiosis, which is a slightly different cell division process that results in the cells having only one copy of each chromosome.
ﾟ+*:ꔫ:*﹤ ﹥*:ꔫ:*+ﾟExplanation:ﾟ+*:ꔫ:*﹤ ﹥*:ꔫ:*+ﾟ
Human body cells (somatic cells) have 46 chromosomes. A somatic cell contains two matched sets of chromosomes, a configuration known as diploid. ... Human cells that contain one set of 23 chromosomes are called gametes, or sex cells; these eggs and sperm are designated n, or haploid.

how do the size and shape of human canines compare with chimp canines
Answer:
Human canines are blunt and small in size, while chimps have big and sharp canines.
Explanation:
Chimps' mouths are larger than humans' mouths. Chimps have a flat palate; and bigger and sharper canines than humans. Also, there is a space between these teeth and the teeth at the front of the mouth. On the other hand, humans' mouths are smaller, which leads to smaller and less sharp canines, and there is no space between these teeth and the teeth at the front of the mouth.
Answer:
Humans are more circular and wide, while chimpanzees are longer and skinnier

Without helicase, predict what would happen during DNA replication
Answer:
Should be D since what the helicase does is unwind the dna and seperate it into the 2 strands
Explanation:
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.

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).

A single cell of testis divides to produce:
a. 4 sperms.
b. 6 sperms.
c. 2 sperms.
d. a single sperm.
Answer:
Each primary spermatocytes goes through the first meiotic division, meiosis I, to produce two secondary spermatocytes, each with 23 chromosomes (haploid). Just prior to this division, the genetic material is replicated so that each chromosome consists of two strands, called chromatids, that are joined by a centromere.
Answer:
Assertion In the testis, spermatogenesis occurs in the seminiferous tubules and testosterone secretion takes place from the Sertoli cells. Reason Testosterone brings growth and maturation of secondary s3x organs and also the development of accessory s3x characters.

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).
