What would MOST LIKELY happen if the sun's gravitational pull no longer existed?
A. The planets would start crashing into each other because without the sun gravity would pull all of the planets together.
B. The planets would float off into space because without the sun inertia would no longer exist, and the planets would stop moving
forward.
C. The planets would float off into space because the gravitational force of the sun would no longer be there.
D. The planets would start crashing into each other because the forward motion of inertia would pull them toward each other.
Answer:
C. The planets would float off into space because the gravitational force of the sun would no longer be there.
Explanation:
I believe this is the answer because a sudden cease in the sun's gravitational pull would cause the planets to continue on a straight path in the direction the sun was pulling them before it ceased to exist.

One explanation for why our sense of smell and language are so disconnected is that
A. smell is only of secondary use to humans, language is of primary use.
B. olfactory information is not integrated in the the thalamus prior to processing in the cortex, and the two systems are primarily processed in opposite hemispheres.
C. there is no need to have connections between smell and language.
D. language developed much earlier in evolution than smell.
E. olfactory information is more widely distributed throughout the brain than is language.
Answer:
B. olfactory information is not integrated in the thalamus prior to processing in the cortex, and the two systems are primarily processed in opposite hemispheres.
Explanation:
The thalamus is the main source of sensory information to the primary sensory cortex except for the sense of smell. The olfactory information from the sensory neurons needs to pass through the thalamus in order to reach the primary sensory cortex. Moreover, different thalamic nuclei, i.e., different groups of packed neuronal cell bodies that form the thalamus, have been involved in language. A bilateral thalamic activation (with left greater than right thalamic activation), as well as the activation of cortical regions associated with the language, is observed during tasks related to language processing. Language information is processed within the left hemisphere, while the olfactory information is processed in the olfactory bulb which is located on the inferior (bottom) side of the cerebral hemispheres.

Amphibians are very sensitive to changes in their environment. Why might this be?
Answer:
Amphibians are known to have very thin, moist skin and lay eggs without shells. Because of this, they are extremely sensitive to biological changes, such as chemicals in the air or water, and climate change. This makes amphibians ecological indicators; this means that amphibians are the first signs of an unhealthy ecosystem. When large amounts of amphibians grow or die, this means there is a problem with the ecosystem.

how might biotic and abiotic factors have affected the tortoises that Darwin observed on the Islands
Answer:
Some Abiotic factors are water, soil, light, temperature. These are non-living things that the tortoises will interact with in the enviornment. These can affect them for example if there is an abundance of water and light then the tortoise population can expand. However if there is too little or too much of these factors then the population will decrease. Biotic factors are plants, animals, bacteria and Protists. These are the living things the tortoises will interact with in the enviornment. Biotic factors can affect them for example if there are too many preditor animals for the tortoises, then their population will be very low and a lot of them will die.
Explanation:
Some Abiotic elements are water, soil, mild, temperature. These are non-residing matters that the tortoises will have interaction with withinside the environment.
These can have an effect on them for example if there may be an abundance of water and mild then the tortoise populace can expand. However, if there may be too little or an excessive amount of those elements then the populace will decrease. Biotic elements are flora, animals, microorganisms,s, and Protists. These are the residing matters the tortoises will have interaction with withinside the environment.What did darwin find on the islands?
He found out that the tortoises had tendencies that allowed them to stay in their precise environments. For example, tortoises that ate flora close to the floor had rounded shells and shorter necks.
Thus it is clear that biotic and abiotic factors have affected the tortoises that Darwin observed on the Islands.

Which statement best describes one of the phases represented in the diagram below? The mature forest will most likely be stable over a long period of time. If all the weeds and grasses are destroyed, the number of carnivores will increase. As the population of the shrubs increases, it will be held in check by the mature forest community. The young forest community will invade and take over the mature forest community.
Answer:
The correct answer is - The mature forest will most likely be stable over a long period of time.
Explanation:
The diagram attached with the answer is a diagram of the ecology succession. Ecology succession is the process of the structure of a biological community that evolved from a pioneer community to a climax community over a time period.
Pioneer community is the community that includes the initial biological species that occurs in a newly established environement that evolved to various types of communities. The final stage of ecological succession is called climax community that is the mature forest here, which is a very stable stage that can present for hundreds of years.

What is Polypeptide?Biopolymers can be divided into four main categories: polysaccharides, polypeptides, polynucleotides, and fatty acids.
A discontinuous chain of amino acids linked together by peptide bonds is called a polypeptide whereas a peptide bond is formed by joining the carboxyl group of one amino acid to the amine group of the following amino acid to form an amide.
Smaller polypeptides depending on how many monomeric amino acids make them up. For example, a peptide called a dipeptide is made up of two amino acid subunits, a peptide called a tripeptide is made up of three amino acid subunits, and a peptide called a tetrapeptide is made up of four amino acid subunits.

1) Explain why a high concentration of salts in the soil tends to reduce transpiration.
2) explain why seedlings have a better chance of survival when transplanted in the evening.
Answer:
The absorption of water by the roots of plants is through the osmotic gradients between the soil and the plants xylem vessels.
The high the osmotic gradients the faster the water uptake though the sieve tubes in the plants. The movement of water from the soil into the roots is by osmosis and root pressure.
In a normal soil Osmosis is the movement of water molecules from the region of higher water potential(soil) to the region of lower water potential(plant roots) though a semipermeable membrane.
Therefore a soil with high salt concentration the higher salt would affect the osmotic potential and few water molecules would be able to move from the roots into the roots. This is because the more salt molecules reduced the water potential for water molecules to move through the root by the root pressure initiated by osmosis to form transpiration pull and stream in stems.
Since the loss of water in transpiration comes from water absorbed by the roots through osmosis, root pressure ,transpiration stem and pull, ,the reduced absorbed water leads to reduced transpiration.
2.
The loss of water from the leaves is through stomata. These are usually open for water loss by transpiration .During evening they are close. Therefore transpiration stream amd pull do not take place, so little water absorbed from the soil and water s conserved in plants.
Thus transplant done during the evening gives the seedlings chances of survival because the closed stomata ensues waters conservation, and less stress on the roots which prevent transpiration through the stomata..

Explanation:

#Carryonlearninh
If at start there are 60 chromosomes and ending with 30 chromosomes, then the process is meiosis. The correct option is C.
What is meiosis?Meiosis is a type of cell division that occurs in reproducing organisms and results in a reduction in the number of chromosomes in gametes (or egg and sperm).
Body (or somatic) cells in humans are diploid, with two sets of chromosomes (one from each parent).
Meiosis is a type of cell division that produces four gamete cells while reducing the number of chromosomes in the parent cell by half.
This process is necessary for the production of egg and sperm cells for reproduction.
Without meiosis, the number of chromosomes in a species does not remain constant across generations and is duplicated every time after reproduction.
Without meiosis, an organism cannot reproduce effectively through reproduction.
As, meiosis is equational division, and the chromosome number is also getting reduced to half, it can be meiosis.

Answer:
The feasibility and profitability of game ranching have been amply demonstrated by a number of studies. The rationale behind advocating game ranching in Africa is that conditions in many parts of' the continent, whether resulting from inadequate rainfall or presence of certain disease organisms' are not appropriate for production of exotic cattle and other domestic stocks. Indigenous wild animal species on the other hand have evolved in the African ecosystem and are better adapted to the prevailing conditions and should therefore be more productive.
Game ranching is currently most developed in southern Africa (particularly South Africa Namibia and Zimbabwe), although a private game ranch, the Galana Ranch, was established in Kenya in the 1970s (King and Heath, 1975; Thresher, 1980). The ranch initially focused on three species: the fringe eared oryx, Oryx beisa callotis, the African buffalo and the eland. Reported advantages of the eland over the Boran cattle included much lower water requirement, faster breeding and growth, earlier maturity and ability to put on weight in grazing conditions under which the Boran cattle began to lose weight and approximately 14 % higher dressing out weight. In addition to these biological and physiological advantages a cost-benefit analysis of maintaining a breeding herd of 11,000 oryx and 5000 Boran on the ranch showed clearly that the financial returns on the oryx was far superior to that of cattle (Thresher, 1980).
Explanation:
I am not interested
Numerous studies have amply shown that game ranching is both feasible and profitable.
What is Argument?
The argument in favor of game ranching in Africa is that the climate in many regions of the continent, whether as a result of insufficient rainfall or the presence of specific disease organisms, is insufficient for the breeding of exotic cattle and other domestic species.
On the other hand, native wild animal species have evolved in the African ecosystem and are better adapted to the current conditions; as a result, they should be more productive.
Although a private game ranch, the Galana Ranch, was founded in Kenya in the 1970s (King and Heath, 1975; Thresher, 1980), southern Africa, particularly South Africa, Namibia, and Zimbabwe, currently has the most developed game ranching industry.
