it’s cells reproduce and die at the same rate
Answer: Option B
Explanation: When the organism has stopped growing then there is no visible growth in the body of the organism.
When the cells proliferate and dies at the same rate, the change is zero and the body seems to be finished growing. This can be described on the cellular basis that the number of cells remains constant as the rate of proliferation and death is same.

Answer:
Tubercle: allows tendons to attach to bone
Foramen: Allows blood vessels and nerves to travel through bone.
Fossa: Allows to bones to form a joint.
Explanation:
Tubercle is a small round prominence on the bone which helps in the attachment of tendons to the bones.
Foramen means aperture or hole, through which blood vessels and nerves can pass through. For example: Vertebral foramen. Vertebral foramen of all the vertebral bones together form the vertebral canal. Blood vessels pass through the vertebral foramen. Another example is foramen magnum in the occipital bone.
Fossa is small depression on the surface of bone where articulation can occur. Example: radial fossa- is a depression which articulated with head of radius when the forearm is raised. Olecranon fossa receives olecranon of ulna when forearm is extended.
What is the independent and dependent variable in this:
"Sandy heard that plants compete for space. She decided to test this idea. She bought a mixture of flower seeds and some potting soil. Into each of 4 plastic cups, she put the same amount of soil. In the first cup she planted 2 seeds, in the second cup she planted 4 seeds, in the third cup 8 seeds, and in the fourth cup 16 seeds. After 25 days she checked to see how many plants had grown and their height."
Answer:
The correct answer will be- the number of seeds in cups.
Explanation:
The scientific experiments involve the parameters which directly controls and help determine the hypothesis. These parameters are known as the variables which could be changed or kept constant.
The variables which could be changed or manipulated by the researcher or can get a change on its own like time are known as the independent variables. The variables which depend on the independent variables and are to be studied are known as the dependent variable.
In the given question, sandy studied the growth pattern and height of the plant which are considered dependent variables but they changed the number of seeds in the cups and thus they will be considered as the independent variables.
Thus, the number of seeds in the experiment represents the independent variables.

Which trend do the data in the maps support ??
i think that the land is warmer
Answer: In the given maps, there shows the temperature anomalies in both land as well as sea surface. In the sea surface, the temperature anomaly ranges from -5°C to 5°C which is comparatively lesser than the land temperature i.e -12°C to 12°C.
Thus from the provided data in the map, we can conclude that the average temperature in the land surface is more than the sea surface because the sea surface has the capacity to reflect back heat to the atmosphere but land surface cannot reflect much of it, thereby becomes more warmer as it absorbs most of the incoming solar radiations.

How do mutations drive evolution?
An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.
well a mutation in a animals DNA is evidence that it may be trying to adapt to its environment. or the mutation is caused be a disease or excessive amounts of radiation. but either way the mutation can be passed down to the next generation. And the mutation can continue to 'evolve' and create new possibility in what the animal can do.
Hope that this helps. Good luck!
A collected gas has a pressure of 778mmHg and a temperature of 47.0C. What would be the new pressure at standard temperature
Answer:
= 664.10 mmHg
Explanation:
According to pressure law the pressure of a fixed mass of a gas is directly proportional to the absolute temperature.
Therefore;
P1/T1 = P2/V2
Standard temperature is equal to 0°C, which is 273.15 K.
In this case;
P1/T1= P2/T2
P1 = 778 mmHg
T1 = 47.0 + 273 K
= 320 K
P2 = ?
T2 = 0° C = 273.15 K
P2 =P1T2/T1
= (778 × 273.15)/320 K
= 664.10 mmHg

What kind of factors are light temperature and soil composition
I think it is abiotic if it is not i am sorry
Answer:
The correct answer is abiotic factors.
Explanation:
A non-living constituent in the environment is known as an abiotic factor. This can be either a physical presence or chemical. The abiotic factors come in three fundamental categories. These are edaphic, climatic, and social. The edaphic factors comprise conditions of the soil, the climatic factor comprises sunlight, humidity, and other factors taking part in the climate. The social factors comprises the water resources in the region, and how the land is used. The five general abiotic factors are chemical elements, atmosphere, temperature/sunlight, water, and wind.

Plants add water to the atmosphere through
Plants add water to the atmosphere through transpiration. Transpiration is the process of water moving through plants and evaporating, becoming water vapor. This water vapor is released into the atmosphere.
Answer:
Transpiration
Explanation:
Vegetal transpiration corresponds to the process of water dispensing in the form of steam, given to the environment through a unidirectional sense, that is, of the water rising from the root region towards the leaves, and from these to the atmosphere. Therefore, we can conclude that it is through plant transpiration that plants add water to the atmosphere.

An object has a kinetic energy of 32 J and a mass of 36 kg, how fast is the object moving?
Answer:
1,34 m/s
Explanation:
KE= 1/2 mv^2
massa = 3,6 × 10 ^4/ 10 ^3 kg = 36 kg
KE = 1/2 × 36 × v^2
32 × 2/36 = v^2
64/36 = V^2
√64/36 = V
V= 8/6
V = 1,34 m/s
Name the substrate the main product and the by-products of fermentation
The two main types of fermentation are alcoholic fermentation and lactate fermentation (there are other types). Sugars are the most common substrate of fermentation, and typical examples of fermentation products are ethanol, lactic acid, carbon dioxide, and hydrogen gas (H2).
Answer & explanation:
The two most important types of fermentation are latic fermentation and alcoholic fermentation.
The lactic fermentation has pyruvic acid as its substrate, this reaction has as its end product the energy in the form of ATP and its byproduct is lactic acid.
In alcoholic fermentation, yeast and some bacteria ferment sugars(substrate), producing at the end of the fermentation reaction energy (ATP) as a final product, and as byproducts carbon dioxide and ethanol.

As the rate of cooling of igneous rocks increases, the size of the crystals that form
As the rate of cooling of igneous rocks increases, the size of the crystals that form decrease. Sense the size of the crystals will decrease, this would include that the rate of cooling of igneous rocks increases.
Answer:
The correct answer is "decreases".
Explanation:
As the rate of cooling of igneous rocks increases, the size of the crystals that form decreases. Volcanic or igneous rocks go trough a cooling process when they reach the Earth's surface, crystallizing and forming different crystal forms. The size of the crystals depend on the cooling rate, slow cooling allow the formation of large crystals, while fast cooling yields small crystals.
