what hellpppp pleaseAnswer: It allows a greater flow of blood to the tissues. It helps in creating more pressure to pump blood around the whole body tissues and organs. A separation of oxygenated and deoxygenated blood is possible that leads to taking in oxygen-rich blood and removal of carbon dioxide from the blood through the lungs.

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.

False answers will be reported but if your answer is good I will give it brainliest.
Physical and chemical properties influence the formation of ocean current and the distribution of marine life through the different features present.
What is Marine life?This is referred to as the animals, plants and other organisms which live in salt water sea and oceans.
Physical and chemical factors such as oxygen levels and light availability promotes the presence of of plants and animals as they are able to undergo photosynthesis and also respire thereby ensuring their increased growth and reproduction.
High ocean current also reduces the amount of organisms present in the marine life due to them being washed away to other parts and hindering their survival.

A. As human population increases, the succession in the rainforest leads to increased biodiversity.
B. As human population increases, the diversity of larger rainforest plant species increases.
C. As human population increases, the number of individual rainforest plant species increases.
D. As human population increases, the diversity of all rainforest plant species decreases.
E. As human population increases, the diversity of all rainforest plant species increases.
Answer:
Answers is the as human population increase the diversity of all rainforest plants species decrease
Explanation:
The effect of an increase in human population most likely to have on the biodiversity of the plant species found in the rainforest will be as human population increases, the diversity of all rainforest plant species decreases. Thus, the correct option is D.
What is Biodiversity?Biodiversity is the term used to describe the enormous variety of life forms which are present on the Earth. Biodiversity can be used more specifically to refer to all of the species which are present in one region or an ecosystem. Biodiversity refers to every living thing, including the plants, bacteria, animals, and the human population living in a geographical location.
An increase in the human population most likely have an effect on the biodiversity of the plant species which are found in the rainforest is that as the human population increases, the diversity of all the rainforest plant species decreases.
Therefore, the correct option is D.

What is ecology?In the ecology study of the interaction between organisms and their abiotic environment, different animal systems play different roles.
In a particular ecosystem, every organism is dependent on others to maintain a balanced life which affects its surrounding environment.
An animal system is a group of animals in a particular habitat that describe a particular species interaction in which an organism interacts with its surrounding environment.
Therefore ecology is the study of connections between different animal systems.

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.

8. Write the process of water absorption by roots in plant
Answer: In higher plants, water is absorbed through root hairs from the soil water. The walls of root hairs are permeable to water and are hydrophilic in nature. They contain vacuoles filled with cell sap. Absorption of water by roots takes place by two mechanisms namely, active absorption and passive absorption. During active absorption, the root cells absorb water using metabolic energy released through respiration. Active absorption could be either osmotic absorption or non-osmotic absorption. In osmotic absorption, water is absorbed from the soil into the xylem of the roots in the osmotic gradient. In non-osmotic absorption, water is absorbed against the osmotic gradient. In passive absorption, water absorption is due to transpiration. In this, absorption of water into the root is due to conditions that originate in the top of the plant and the root cells play a passive role. Osmotic concentration of the root cells is due to the presence of soluble metabolic products synthesized in the aerial parts of the plants and later translocated downwards to the root cells.

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.

include milk and dairy products,eggs, meat (beef, pork, and lamb), and cut leafy greens.Example of CUT LEAFY GREENS are the chopped celery. They must be transported to the serving site at 41F or below because they provide a medium that readily supports the growth of pathogens when they are held without temperature control after the internal fluid and nutrients are exposed by cutting the leaf.
