Answer:

logistic, exponential, death, level off

Explanation:

A population can show two types of growth. Exponential growth occurs in ideal conditions when the resources like space and food are unlimited. The population keeps growing exponentially thus showing a J shaped curve. In real life though, logistic growth model is observed. The population starts growing but after it reaches its carrying capacity (maximum number of individuals that can be sustained), it levels off i.e. it stays slightly above or below the carrying capacity, almost like being constant.

Birth rate determines the number of live births per 1000 people in a population. Death rate determines number of deaths per 1000 people in a population. If both of them become equal, it means that there is no effective increase or decrease in population hence zero population growth.

Where are your blood cells made
Alexeev081 [22]

Red blood cells. Red blood cells (also known as erythrocytes) are cells in the blood that carry oxygen to all parts of the body. They are made in the spongy marrow inside the large bones of the body. Bone marrow constantly makes new red blood cells to replace old ones.



. In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water, and contains proteins, glucose, mineral ions, hormones, carbon dioxide, and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells, white blood cells and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is mostly transported extracellularly as bicarbonate ion transported in plasma.

How did each change to the land affect the fish in the pond?
N76 [4]
<span>Lakes and ponds are inland bodies of standing or slowly moving water. Although lakes and ponds cover only 2 percent of the world's land surface, they contain most of the world's fresh water. Individual lakes and ponds range in area from a few square meters to thousands of square kilometers. In general, ponds are smaller than lakes, though regional idiosyncrasies of naming abound—Henry David Thoreau's famous Walden Pond in Massachusetts has a surface area of 64 acres. Lakes and ponds are an important source of fresh water for human consumption and are inhabited by a diverse suite of organisms.</span>

During the cell cycle, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell
Yuliya22 [10]

Uncontrolled production of cyclins will most likely result in uncontrolled division of the cell.

CELL DIVISION:

  • Cell division is a biological process that every cell undergoes to replicate themselves. It is the process by which cells are multiplied in living organisms.

  • According to this question, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. However, at the end of the cycle, the cyclins are degraded to prevent further signaling for the cell to divide.

  • In a case whereby there is an uncontrolled production of cyclins, this will most likely result in uncontrolled division of the cell because cyclins stimulate cellular division.
