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

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.
Which of the following is NOT one of the three global wind patterns?
A. Polar Easterlies
B. Westerlies
C. Trade Winds
D. Interglacial Winds
Answer:
I believe that the correct answer is d. Interglacial Winds
Explanation:
Please mark as brainiest ! Hope this helps!
Polar Easterlies, Westerlies and trade winds are the three main global wind patterns. Interglacial winds are not a type of global wind patterns. Thus, the correct option is D.
What are global wind patterns?Global Wind Patterns is mainly the result of a thermodynamic principle and the Coriolis effect due to the counterclockwise rotation of the planet earth. Warm air around the equator is lifted that creates a suction effect for air masses coming from different latitudes.
The three important global wind belts are polar easterlies, westerlies, and trade winds. The polar easterlies flow from the north and south poles towards 60° north and south, respectively. They are very cold and dry winds. The westerlies are present between 30° and 60° north and south of the Equator.
Therefore, the correct option is D.

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.

Explanation:
When two members of the same species (male and female) mate, they produce fertile offspring.
The conclusion that can be drawn from this is that due to the fact that from looking at the scientific names of the animals, there are different genus and species names, there would be no interbreeding between them as they do not belong to the same species.
And if peradventure there is crossbreeding, the union would be unable to produce fertile offspring.

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.

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.

Explanation:
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.
