All members of a population share the characteristic of belonging to the same species. Therefore, the correct option is C.
What is a population?A population is defined as a group of organisms of the same species that live in the same geographic area and are able to interbreed with one another. This means that they share many common traits and characteristics, such as physical appearance, behavior, and genetic makeup.
Option a (temporal isolation) and option b (geographic isolation) are not the characteristics that all members of a population share.
Option d (identical genes) is also not correct, as members of a population may have genetic variation due to mutations, genetic recombination, and other factors. Therefore, the correct option is C.

In non-muscle cells, a small increase in the cytosolic concentration of Ca2 can have a dramatic effect on several physiological processes. The presence of a specific protein in the cytosol, however, activates a Ca2 ATPase that serves to return these elevated cytosolic Ca2 levels back to basal levels, thereby maintaining the cell's normal physiology. Which protein is directly involved in activating this Ca2 ATPase
Answers
Answer:
calmodulin
Explanation:
The calcium-modulated protein (calmodulin) is a calcium-binding receptor protein that modulates contractile proteins (i.e., actin and myosin proteins) of the skeletal muscle and non-muscle cells (e.g., platelets). Calmodulin binds to calcium ions (Ca2+) and subsequently activates a number of Ca2+ dependent enzymes (e.g., kinases or phosphatases), which finally activate/deactivate proteins in the calcium signal transduction pathway. Ca2+-ATPase pumps in the membranes of eukaryotic cells release Ca2+ from the cytoplasm and they are autoinhibited by low Ca2+ levels, while calmodulin-binding releases this autoinhibition and thus activates the pumps. In non-muscle cells such as platelets, calmodulin also mediates Ca2+ control of actin-myosin interaction by phosphorylation of the myosin light chain (MLC).

The picture below represents which
stage of photosynthesis?
A. Dark reactions
B. Calvin Cycle
C Glycolysis
D Light reactions
Answers
It represents Glycolysis, a key metabolic route that produces energy and generates precursors for the production of primary metabolites in plants. Thus, option (C) is correct.
What is photosynthesis ?
Green plants and certain other organisms convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.
The first method of breaking down glucose to release free energy is called glycolysis .Two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water are produced during glycolysis.
Hence, the picture depicts the process of gylcolysis , stage of photosynthesis i.e option (c)

Without knowing the genetic differences of the birds, how can we know that cardinals and finches are likely more closely related to each other than cardinals and finches are to woodpeckers? Cardinals and finches live in more similar habitats. There is no difference in their relatedness; because they are all birds, they all evolved at the same time from a common ancestor. Cardinals and finches have more morphological similarities. Fossil records show that cardinals have been around longer than woodpeckers and sparrows.
Answers
Answer:
The correct answer is - Cardinals and finches have more morphological similarities.
Explanation:
To find out the relatedness of the different species or organisms one can use genetic mapping to find precise relatedness, however, if one can not find the genetic differences of the organism one can use the morphological similarities and differences to find out how closely they are related.
Homologous structures and analogous structures are two major morphological characters to find how closely related cardinals and finches are than cardinals and finches are to woodpeckers.

Claim: This process uses expensive fertilizers and pesticides to grow pest free crops which may be produced in excess. Explain the reasons why people would go against growing wheat this way.
Your answer: Here are 3 reasons that go against growing wheat this way.
1. The fertilizers and pesticides are expensive and cost farmers a lot which takes away from the revenue that farmers make from growing the crops in the first place.
2. Other then fertilizers and Pesticides its a lot of work as you can see on the chart throughout the year there are many things you must do too keep crops bug free and pest free this reason I'm explaining says that taking and doing all of this work for not pests/bugs is too much and not needed.
3. Fungicide Is needed a lot and incredibly expensive when you used/spray it on crops that much and point goes a lot more for large crops too.
If these reasons don't work, find factors that or counterclaims that go against this method of harvesting wheat. (This is what your supposed too do)

El agua se mueve del cuerpo de agua a la atmósfera debido al proceso de evaporación en forma de vapor. A medida que los vapores de agua se enfrían, el agua se condensa en gotitas y forma nubes que resultan en precipitaciones en forma de lluvia y nevadas. Los vapores de agua se vuelven más pesados cuando se condensan y debido a su cuerpo pesado no pueden permanecer en la atmósfera por lo que caen a la tierra en forma de lluvia y nevadas.
