Explanation:
An ecologist in Costa Rica wanted to determine the PGR for the country in 2018, and collected all of the data necessary to calculate the rate. She concluded that there were 34,560 births and 2,310 deaths within their population of 100,000. There were also 478 immigrants and 126 emigrants that year. What was the population growth rate for Costa Rica?
The population growht rate is 32.602 % per year. Population growth can be calculated as = (births + immigrants) - (deaths + emigrants).
In this case, population growth is equal to = (34,560 births + 478 immigrants) - (2,310 deaths + 126 emigrants) = 32,602 new individuals per year
Total (original) population: 100,000 _____ 100%
32,602 _____ X
In consequence, the population growth rate per year can be estimated by the following equation:
X = (32,602 x 100)/ 100,000 = 32.602 %

what enzyme catalyzes the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate?
Water is reabsorbed during filtration by renal capillaries.
Answer:
Most of the solutes get reabsorbed in the PCT by a process called tubular reabsorption. In the loop of Henle, the filtrate continues to exchange solutes and water with the renal medulla and the peritubular capillary network. Water is also reabsorbed during this step.

Which graphic organizer best compares the energy inputs and outputs of cellular respiration
and photosynthesis?
A)
А
B)
B
c
C
D)
D
Answer:
B
Explanation:
I believe it is #B because light and energy are what's needed for plants to begin the photosynthesis cycle, which then produces chemical energy which in turn contributes to cellular respiration ect.
I hope this helped :)
The graphic organizer best compares the energy inputs and outputs of cellular respiration and photosynthesis - B. Light energy → photosynthesis → chemical energy → cellular respiration → chemical energy.
Energy transfers from one cellular reaction to another, it changes its form from one type of energy to another. In photosynthesis and cellular respiration energy converts as follows:
photosynthesis: In this cellular process light energy is trapped that helps in the conversion of inorganic matters to organic matter which stores energy in the form of chemical energy called glucose.cellular respiration: The products of photosynthesis are glucose (stored chemical energy) and oxygen converted in the carbon dioxide and water with ATP a chemical compound that stores a high amount of energy.Thus, The graphic organizer best compares the energy inputs and outputs of cellular respiration and photosynthesis - B. Light energy → photosynthesis → chemical energy → cellular respiration → chemical energy.

What causes muscles to get sore?
When muscles are required to work harder than they're used to or in a different way, it's believed to cause microscopic damage to the muscle fibres, resulting in muscle soreness or stiffness. DOMS is often mistakenly believed to be caused by a build up of lactic acid, but lactic acid is not involved in this process.

Why do you think there are more organisms and energy available for life in the producer level?
Answer:
Producers which means plants have the most energy in a food chain or web besides the sun and they give an organism more energy than a primary consumer or secondary consumer would. Plants absorb about 1% of the sunlight that strikes them. The rest is reflected into space or transmitted through objects.
Which of the following is a product of cellular respiration?
Carbon dioxide
Oxygen
Carbon monoxide
Nitrogen
Answer:
it Carbon dioxide and water but Carbon Dioxide was the only one here
Explanation:
The one that is a product of cellular respiration is carbon dioxide. The correct option is A.
What is cellular respiration?Cellular respiration is the process by which biological fuels are oxidized in the appearance of an inorganic electron acceptor such as oxygen to yield huge amounts of energy, which drives the bulk production of ATP.
In plants, photoautotrophic processes are used to obtain the glucose required for cellular respiration. This means that plants can use the light energy they receive from the sun to produce glucose and oxygen.
ATP is the primary product of cellular respiration; waste products include carbon dioxide and water.
All through cellular respiration, one sugar molecule is converted into 38 ATP molecules. The electron transport system actually creates 34 molecules of ATP out of a total of 38 molecules.
Thus, the correct option is A.

Explanation:
Each organ is made up of several different types of tissue. Therefore, for every organ in the body, there are many more tissues.
Answer: Venn diagram of exocytosis , diffusion , endocytosis , osmosis is
described below.
Explanation:
Exocytosis: refers to the process by which the contents of a cell are released to the exterior environment through fusion of the vacuole membrane with the cell membrane.
Endocytosis: refers to the process in which cells take the material from outside the cell by taking in the vesicle. These materials serve as nutrients and pathogens which help cell to fight against foreign diseases.
The common thing these two process have among them is
FlagellaPlasma MembraneCell divisionCytoplasmRibosomes chromosomesDiffusion: It is the process of movement of molecules from through a
semipermeable membrane from the region of higher concentration to lower concentration.
Osmosis: The movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's fractionally permeable membrane.
