1. What is density dependence, and why is it important in multicellular
organisms?
Answer: It is when the population growth rates are regulated by density of a population. This is important in a multicellular organism for several reasons. It would affect the birth and death rates of the organism.
Explanation:
Density dependence refers to the dependence of population growth on density. Natality and mortality rates depend on the number of individuals. The concept is closely related to competition between individuals for resources.
---------------------------
The concept is related to the logistic growth model.
Populations that express a logistic growth model are mostly composed of multicellular organisms.
Population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate.
The population per capita growth rate decreases as population size increases.
While growing, the population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get equal to each other.
Assuming that population size is N, when
N<K, the population can still grow. N approximates to K, the population´s growth speed decreases. N=K the population reaches equilibrium, N>K, the population must decrease in size because there are not enough resources to maintain that size.Usually a sigmoid curve represents the logistic growth model.
So what does it mean?
That the natality and moratality rate depends on the number of individuals in the population.
As the population grow, the number of individuals increases, and competition for resources increases.
When the population reaches the critical point of being equal to carrying capacity, means that the environment can not support more individuals.
There are not enough resources for all of them, and competition increases affecting the reproductive rate and population growth.
So after this point, the population size decreases.

the process of releasing material from inside the cell
You can be referring to exocytosis which removes waste from inside of the cell which requires ATP.
. In centaurs, the allele for curly tails (T) is incompletely dominant to the allele for straight tails (t). The hybrid genotype results in wavy tails. In a population of 1500 centaurs, 315 have curly tails, 820 have wavy tails, and the remainder has straight tails.
a. Determine the allele frequencies of: T = ____________ t = ____________
b. Determine the genotype frequencies of TT = ___________ tt = ____________
Answer:
a. Determine the allele frequencies of:
f(T) = 0.485 ≅ 0.48 f(t) = 0.515 ≅ 0.52b. Determine the genotype frequencies of the exposed generation
F (TT) = 0.21 F (Tt) = 0.55 F (tt) = 0.24the genotype frequencies of the next generation

How are vesicles involved in endocytosis and exocytosis?
Answer:
Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell. Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.
Answer:
Explanation:
The walls of vesicles are also made up of a lipid bilayer, which is why they are capable of fusing with the cell membrane. This fusion between vesicles and the plasma membrane facilitates bulk transport both into and out of the cell.

Explanation:
The graph shows how a Serengeti Buffalo population changed over a period of years. At the beginning of the time period, the buffalo were affected by the Rinderpest virus, a debilitating disease with a high mortality rate. However, within five years, the virus was eliminated. After Rinderpest was eliminated, what was the ecosystem's carrying capacity for buffalo, based on the graph?
Population Growth of Serengeti Buffalo
A.
60,000 buffalo
B.
35,000 buffalo
C.
55,000 buffalo
D.
65,000 buffalo
Answer:
Yes its 60,000
Explanation:
Based on the graph, after Rinderpest was eliminated, 60,000 was the ecosystem's carrying capacity for buffalo. So, the correct option is A.
What is Carrying capacity?The greatest number of a biological species that can be supported by a given environment, given the availability of food, habitat, water, and other resources, is known as the carrying capacity of that ecosystem. The typical population size of a species in a given habitat is referred to as carrying capacity.
Environmental elements including sufficient food, shelter, water, or mates are able to control the population number of the species. The population will decline until the resource recovers if these needs are not supplied. Another way to think of carrying capacity is as the population size when the population growth rate is zero. Based on the given graph, after Rinderpest was eliminated, 60,000 was the ecosystem's carrying capacity for buffalo.
So, the correct option is A.

21. A 300 N force acts on a 25 kg object. The acceleration of the object is
7500m/s
300 m/s
25m/s
12m/s
Answer:
[tex]\boxed {\boxed {\sf 12 \ m/s^2}}[/tex]
Explanation:
Force is the product of mass and acceleration.
[tex]F=ma[/tex]
The mass is 25 kilograms and the force is 300 Newtons, but we should convert the units to make the problem easier later.
1 Newton is equal to 1 kilogram meter per square second. The force of 300 N is equal to 300 kg*m/s²Substitute the known values in for the variables ( F and m).
[tex]300 \ kg*m/s^2= (25 \ kg) a[/tex]
Since we are solving for a, we must isolate the variable. a is being multiplied by 25 kilograms and the inverse of multiplication is division. Divide both sides by 25 kg.
[tex]\frac{ 300 \ kg*m/s^2}{25 \ kg}= \frac{(25 \ kg) a}{25 \ kg}[/tex]
[tex]\frac{ 300 \ kg*m/s^2}{25 \ kg}= a[/tex]
The kilograms will cancel out (hence our earlier unit conversion).
[tex]12 \ m/s^2=a[/tex]
The acceleration is 12 meters per square second.

Explain, using a named example, why many sex-linked diseases occur more frequently in men than women
Answer:
Because men have Y-chromosomes.
Explanation:
In women, the final chromosome is XX, but in men, it is XY. Because this Y gene is different, genetic disorders are typically linked to this chromosome. A mutation in the X chromosome is equally prevalent in the population, meaning that the Y chromosome makes a male more likely to have a disease because they are more likely to have a genetic disorder, due to having both an X and Y chromosome.

Explain how the random motion of water molecules causes the Brownian movement of the fat gobules.
Will give brainliest!
Answer:
Hey brainer! Brownian Motion is the random motion of large particles caused by the motion of the much smaller molecules that are all around them. In the case above, the circles you see are the fat globules in milk suspended in water as viewed through a web-cam down a microscope. The globules vary in diameter from 0.5 to 5 micrometres. The water in which they are suspended is made of H2O molecules with are typically 0.0003 micrometres across. The picture below tries to capture scale – but I haven’t managed to draw the water molecules small enough. Brownian motion is the jiggling of the gigantic fat globules due to the motion of the tiny water molecules.
