Answer:
See explanation
Explanation:
According to the theory of evolution,species which are better adapted to their environment tend to survive and reproduce in a population passing on these favourable characteristics to their offsprings.
During sexual reproduction, genes can be arranged in new ways from chromosomal crossing over and recombination. This introduces new gene combinations(genotype) and ultimately variation in the population.
This variation may also lead to the observation of new phenotypes in the population.
Describe two specialized cells in the respiratory system that enable the lungs to function?
Answer:
Respiratory epithelial cells line the respiratory tract from trachea to bronchi into bronchioles and alveolar sacs. ... The goblet cells produce and secrete mucous to trap pathogens and debris within the airway tract. Basal cells are progenitor cells that differentiate into cells types found within the epithelium.

Which of these is the main cause of habitat fragmentation? O A. Reduction in genetic diversity O B. Migration of mammal species O C. Demand for land use O D. Extinction of bird species
Answer:
C. Demand for land use
Explanation:
Habitat fragmentation usually occurs because of human activities such as new roads, parking lots, and housing developments. Organisms need their specific habitat for survival, and fragmentation is a leading threat to many terrestrial animals.

The celiac ganglion ________. Group of answer choices is located near the base of the superior mesenteric artery arises from the greater splanchnic nerve projects postganglionic fibers that innervate the small intestine and the kidney and urinary bladder arises from the lesser splanchnic nerve arises from the lumbar splanchnic nerve
Answer:
The correct answer is ''arises from the greater splanchnic nerve''
Explanation:
The greater splanchnic nerve or great adrenal nerve, originates in the thoracic sympathetic chain from vertebral levels T5 to T9 (T10). It runs over the bodies of the thoracic vertebrae and as it descends it becomes more anterior. It enters the abdomen crossing the diaphragmatic pillar and ends at the celiac plexus. The upper part of each celiac ganglion continues with the greater splanchnic nerve. The collateral or prevertebral ganglia innervate the abdominal and pelvic organs and viscera. The celiac ganglion receives preganglionic fibers from T5 to T12 and innervates the stomach, liver, pancreas, gallbladder, small intestine, spleen, and kidneys.

This organ stores the main metal ion that forms part
of the red blood cell. Which ion is this, and what
molecule is it a part of inside the red blood cell?
Answer:
a. Iron (Fe) ion
b. Haemoglobin
Explanation:
Red blood cells (RBC), also known as erythrocytes, are one of the cells found in the blood. Red blood cells are the major components of the blood involved with the transport of oxygen throughout the body. Red blood cells are able to do this because they contain proteinous molecules called HAEMOGLOBIN.
Haemoglobin is a molecule that contains hemic iron groups. Haemoglobin is composed of an IRON ION at the core of its structure, which binds to oxygen atom. Hence, according to this question, haemoglobin is a proteinous molecule that contains iron-binding heme groups in the red blood cells.
What are the govermental and and non governmental organizations working in the field of awareness and what are the measures taken by them
Answer:

Why do cells use fat and starch for long-term energy storage instead of ATP molecules?
O ATP is used for long-term storage, while fat and starch are used for immediate energy.
O ATP is used for short-term energy and to build molecules of starch and fat.
O Fat and starch are unstable and can be stored short-term, while ATP molecules are stable and stored long-term.
O Fat and starch are stable if used as energy immediately, while ATP is used as long-term storage.
Answer:
Cells use fat and starch for long-term energy storage instead of ATP molecules because fat and starch are more efficient energy storage molecules than ATP.ATP is a molecule used for immediate energy, not for long-term energy storage.
Fat and starch are complex carbohydrates that can be broken down to release energy. Fat molecules are primarily composed of carbon and hydrogen, while starch is made of glucose molecules.Both fat and starch can be broken down through cellular respiration to produce ATP molecules that can be used to power various cellular processes.
However, because fat and starch molecules contain more chemical energy than ATP, they can provide a much larger amount of energy over a longer period of time.
Furthermore, ATP molecules are relatively unstable and cannot be stored for long periods of time, while fat and starch can be stored in specialized cellular structures for long-term energy needs.

What type of organisms make up the majority of life on the surface of the pelagic zone?
chemosynthetic bacteria and invertebrates
seaweed and fish
mollusks and seaweed
plankton and algae
The types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae. That is the last option, as plankton and algae are the primary producers in the surface layer of the pelagic zone.
What are the zones of water?
The pelagic zone is the open ocean area that comprises the largest ecosystem on Earth. It is divided into different layers depending on the depth and amount of sunlight that penetrates the water. The surface layer of the pelagic zone, also known as the photic zone, is the layer that receives enough sunlight for photosynthesis to occur, and it is where most of the ocean's primary production takes place.
Hence, the types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae, which is the last option.

In 1970, Frye and Edidin published research describing the mobility of plasma membrane proteins. They fused mouse and human cells together, creating a hybrid cell, and then examined the localization of mouse and human proteins over time. Initially mouse and human proteins were each restricted to one-half of the heterokaryon, but over time the mouse and human proteins mixed, with each being present over the entire cell surface. What technique did Frye and Edidin likely use to examine the mouse and human proteins
Answer:
The answer is "fluorescent microscopy".
Explanation:
A microscope featuring fluorescence is just the same as a conventional light microscope with additional features. Conventional microscopy employs visible light (400-700 nanometers) to illuminate and generate an enlarged image data. Scientists use this highly sensitive, precise, dependable, extensively to see the location of chemicals in tissues and macrophages in organs.

It is believed that the ratio of cyclic electron transport to Z-scheme photosynthesis changes in response to metabolic demands. If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, how would it alter these processes compared to a plant just performing the Calvin cycle to produce glucose
Answer:
The correct answer is (b) More Z-scheme photosynthesis, less cyclic photophosphorylation
Explanation:
Z-scheme is the schematic flow of the electrons from water to NADP+ and as it connects the two different photosystems that look like z in the diagram it is termed as Z-scheme of photosynthesis. The ratio of cyclic electron transport to Z-scheme photosynthesis alters as per the metabolic requirements. In the question, it is given that If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, then it will acqiuire more z-scheme photosynthesis compared to a plant just performing the Calvin cycle to produce glucose.
Answer: More Z-scheme photosynthesis, less cyclic photophosphorylation
What kind of question would an ancient myth try to answer?
How are the moon and the tides connected?
What minerals cover the surface of the moon?
Which phase of the moon is most beautiful?
Why does the moon get smaller and disappear?
Answer:
why does the moon get smaller and dissapear?"
Explanation:
One of the questions that ancient mythology would try to answer would be "why does the moon get smaller and dissapear?" Ancient mythology stories always try to explain everyday occurrences in individuals lives that did not really have a simple explanation at the time due to lack of knowledge. Therefore, these stories usually involved the acts of deities to explain the different unknown events in the world such as the moon dissapearing, shooting stars, volcanoes, hurricanes, etc.
