Answer:
10%
Explanation:
We use the energy pyramid to figure this out:
.01% - A pex Predators
0.1% - Tertiary Consumers
1% - Secondary Consumers
10% - Primary Consumers
100% - Primary Producers
Cows are primary consumers, as they eat grass and hay (which are primary producers). So however much they eat of grass and hay, you multiply by 10% to get the total amount of energy that the cow gets.
Based on your understanding of the process of photosynthesis, what are the strengths and weaknesses of this model?
Answer:
photosynthesis is the process of making food by plant in presence of sunlight and chlorophyll in necessary condition is called photosynthesis .
i think its strength are,
1. it converts the light energy, co2and water inthe form of glucose.
2. it manufactures oxygen during this process.
some weakness are,
1. if there is no sunlight then this process cannot be performed.
2. it may take a long time to do this process.
hope it helps uh..
Answer:
The model’s strength is that it clearly shows that the process is quite complicated and that it takes place in different parts of the chloroplasts. It also shows most of the major molecules produced. But it doesn’t show the major steps of the Calvin cycle, so that’s a weakness of the model. It also doesn’t clearly show the process of the electron transport chain.

Why do developed countries have lower growth rates than less-developed countries? higher birth rates lower death rates higher death rates lower birth rates
The correct answer is D. Lower birth rates
Explanation:
The growth rate is determined by how fast the population of a country or a zone increases. This factor is higher in developing countries than in developed countries. One factor that contributes to this is the low birth rate in developed countries as people have fewer children in these countries, and therefore there are fewer births per year than in developing countries. This is influenced by the accessibility to contraceptive methods, higher education levels, and cultural values. Also, fewer births mean the population will grow slowly, and therefore the growth rate is lower.
Answer:
lower birth rates
explain the structure of nephrons
Structure of nephron : The filtration units in the kidney are called nephrons. Each kidney has a large number of nephrons which are packed closed together. Nephrons consist of a cup shaped Structure called Bowman's capsule in which a cluster of very thin walled blood capillaries form glomerulis . This cup shaped structure is followed by long tubular structure which is convoluted , twisted and finally leads to the collecting duct.
Functions of nephron : : Nephrons help in filtering nitrogenous waste from the blood. The blood entering the glomerulus contains waste which are filtered in the Bowman's capsule. The filtrate formed may contain some useful substances such as glucose, amino acids, salts and a major amount of water. These are selectively reabsorbed as the urine flows along the tube, The amount of water reabosrbed depends on how much excess water is there in the body andhow much dissolved waste there is to be excreted .
* For structure of nephron * refer to attachment !

What is the Hepatic Portal Vein?
Answer: The hepatic portal vein is one of the most important vein that receives blood from the body and transports it into the liver for filtration and processing. This vein is part of the hepatic portal system that receives all of the blood draining from the abdominal digestive tract, as well as from the pancreas, gallbladder, and spleen.
‘Hepatic’ means of or relating to the liver, therefore the hepatic portal vein is a blood vessel that sends nutrient-rich blood from the gastrointestinal tract and spleen to the liver, but also delivers toxins to the liver that will be chemically modified in the proces of detoxication
Answer:
Explanation:
hepatic portal vein is located in the upper right quadrant of the abdomen. It is typically 8 centimeters long in adults. The portal vein is responsible for carrying blood from the GI tract, gallbladder, pancreas, and spleen to the liver.The hepatic portal vein originates behind the neck of the pancreas and is usually formed by the convergence of the superior mesenteric vein and the splenic vein, referred to as the splenic-mesenteric confluence.

transport proteins in the cell membrane play an important role in cell transport by
Answer: Membrane transport proteins are specific and selective for the molecules they move, and they often use energy to catalyze passage. Also, these proteins transport some nutrients against the concentration gradient, which requires additional energy.
Explanation:
Membrane transport proteins play a crucial role in the movement of solutes across biological membranes, including ions, nutrients, neurotransmitters, and a wide range of medications.
What function do transport proteins provide in living membranes?
The cell membrane contains transport proteins that enable the selective transit of particular molecules from the surrounding environment. Each transport protein recognizes a certain chemical only (indicated by matching colors)
The two main kinds of membrane transport proteins are carrier proteins and channel proteins. The specific solute to be transported is bound by carrier proteins (also known as carriers, permeases, or transporters), which then go through a series of conformational changes to move the bound solute across the membrane.

what is a cation????
Answer:
A positively charged ion.
Explanation:
A cation is a positively charged ion. Its opposite would be an anion, a negatively charged ion. An ion is simply a charged (positively or negatively) atom or molecule.
Answer:
Hey mate, here is your answer. Hope it helps you.
Explanation:
A cation is a positive charged ion which has more protons than electrons. If a cation needs to be formed one or more valence electrons should be lost so that there are more of protons. Anion is a negative charged ion which has more electrons. If anion needs to be formed then one or more protons should be lost.
The size of the stem increases in the width due to the ........... meristem.
Answer:
Intercalary
Explanation:
There are three types of meristems : apical, lateral and intercalary.
These are found at different parts of the plant, but their ultimate job is to multiply and so increase the length of the plant.
The length of the stem is determined by the apical meristem, which is found at the tip of the plant.Of this meristem múltiples, the plant grows taller.
The root of the meristem is determined by the lateral meristem, which is found at the bottom of the plant, near the roots.
The thickness of the plant is determined by the intercalary meristem, which is found at the centre of the plant, and when they multiple, the plant increases in width.
Hope this helps.
Good Luck.

The field of science that would be most helpful to an environmental scientist studying the impact of climate change on mangroves in a community is B. Botany.
What is cell?A cell is the basic unit of life that makes up all living things, including animals, plants, fungi, and bacteria. It is the smallest structural and functional unit of an organism that is capable of performing all the functions of life, including metabolism, growth, reproduction, and responding to stimuli. A typical cell is composed of a cell membrane, cytoplasm, and a nucleus (in eukaryotic cells), or a nucleoid region (in prokaryotic cells). The cell membrane is a selectively permeable membrane that surrounds the cell and separates it from the environment, regulating the exchange of materials between the cell and its surroundings.
Here,
Botany is the branch of biology that deals with the study of plants, including their structure, physiology, genetics, ecology, and evolution. An environmental scientist studying the impact of climate change on mangroves would need to have a strong background in botany to understand the biology and ecology of mangroves, such as their growth patterns, reproductive strategies, and responses to environmental stressors. They would need to understand how mangroves are adapted to their environment, how they interact with other organisms in the ecosystem, and how they are impacted by climate change.

what is the meaning of photosynthesis
Answer:
Photosynthesis is the process by which plants and other things make food.It is an endothermic (takes in heat) process.Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy.
Explanation:(what happens in this process)
-Sunlight energy is converted into chemical energy by using chlorophyll.Gives plants their green color to the plants.
- Chlorophyll absorbs red and blue light and uses the energy to convert water and carbon dioxide into glucose.
- Plants convert sugar and energy from water, air and sunlight into energy to grow
- formula for photosynthesis : 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy
-formation of carbohydrates from carbon dioxide and a source of hydrogen in the chlorophyll-containing cells (as of green plants) exposed to light.
- Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis .
- plants breath in carbon dioxide and breath out oxygen.

increases the lethality of T-cells.
eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.
Answer:
The correct answer is - eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.
Explanation:
Self-testing in the immune system is a very important step as it helps in analyzing if the immune cells or lymphocytes. To fight against the intruders, the immune system should initially recognize them. That is, the immune system must have the option to recognize what is nonself (remote) based on what is self. The immune system can make this identification since all cells have distinguishing recognition molecules (antigens) on their surface.
Self-test helps in identifying and eliminate in all lymphocytes that have built and attack the healthy cells and killing them.

lant cells can synthesize energy-rich organic molecules, and later break them down to extract that energy for performing life processes where does it occur?.
Answer:
Two processes were described in this question, hence, the location of the two processes are as follows:
synthesize energy-rich organic molecules- CHLOROPLAST
Break them down to extract energy- MITOCHONDRIA
Explanation:
Plant cells are unique cells capable of synthesizing their own food via a process called PHOTOSYNTHESIS. The process of photosynthesis, which occurs in an organnelle called CHLOROPLAST, synthesizes a sugar (glucose), which is an energy-rich organic molecules i.e. it stores energy in its chemical bonds.
However, to harness the usable form of energy stored in the chemical bonds of Glucose, the cells need to break down the glucose molecule. Plant cells break down glucose in a process called CELLULAR RESPIRATION in order to convert the stored energy in Glucose to a usable form called ATP. This extraction of ATP molecule needed for every life process of the plant cell is carried out in another organnelle called MITOCHONDRION.
During exercise, sensory receptors detect changes in oxygen and carbon dioxide levels in the blood. This information is then sent to the brain's medulla, which causes the heart to beat faster and increases the rate of breathing. Exercising also causes the nervous system to signal the pancreas and thyroid gland to release hormones which regulate metabolism. Which statement is best demonstrated by this scenario? A. Hormones act as signal molecules between all body systems. B. Exercise is important for the body to function properly. C. Nerves transmit and respond to every major system in the body. D. Increased heart rate and blood flow decrease oxygen supply.
A. Hormones act as signal molecules between all body systems
Peripheral Chemoreceptors (Carotid + Aortic Bodies) and Central Chemoreceptors in the Medulla Oblongata detect high Carbon Dioxide levels in the blood during exercise. The respiratory centre in the Medulla Oblongata + PONS stimulate the intercostal muscles and the diphragm to contract in order to increase the rate and depth of breathing as to decrease levels of Carbon dioxide in the blood.
The thyroid gland secretes thyroxine which speeds up metabolism (the rate at which cells use glucose)
