Answer:

{\boxed{\boxed{\tt { Arteries}}}} \

✏ Arteries are the vessels that carry blood away from the heart to various organs of the body.Since, the blood emerges from the heart under high pressure, the arteries have thick, elastic walls.

Consider the functions of the kidney in the urinary system and the blood vessels in the circulatory system. what tissue type is
Bess [88]

Connective tissue is the type of tissue common to the blood in the circulatory system and kidneys in the excretory system.

Renal fascia and blood are two different connective tissues found in the excretory system and circulatory system respectively. All the connective tissues have a common origin, known to be mesodermal. Moreover, they connect two different body parts. Blood connects the body organs and the renal fascia in the kidneys connect the kidneys with the adrenal glands.

Functions of renal fascia and blood are as follows:

Renal fascia (alternatively called gerota's capsule or gerota's fascia) is surrounded by two layers of adipose tissue. The primary function of this tissue involves holding up these tissues and providing a firm hold to protect them from any injury caused by unexpected accidents.

Blood is composed of four main components, plasma, platelets, erythrocytes (RBCs), and leukocytes (WBCs). Some of its functions include:

● The primary function of blood is to supply oxygen to the cells, tissues, and organs in the body

● supplying nutrients and minerals to the body's organs

● removing carbon dioxide and other waste materials like lactic acid, and urea.

● helps in regulating body temperature

● helps in the clotting process during the time of any injury through the action of platelets

● helps in fighting against diseases and infection through the action of WBCs.

tumor cells: tumor cells

Researchers from Harvard Medical School, Boston, and the Institute for Systems Biology, Seattle, have discovered that the remains of tumor cells killed by chemotherapy or other cancer treatments can actually stimulate tumor growth by inducing an inflammatory reaction. The study also reveals that a family of molecules called resolvins can suppress this unwanted inflammatory response, suggesting new ways to enhance the effectiveness of existing cancer therapies

Conventional, radiation- and drug-based cancer therapies aim to kill as many tumor cells as possible, but the debris left behind by dead and dying cancer cells can stimulate the production of proinflammatory cytokines, signaling molecules that are known to promote tumor growth.

“Dead and dying tumor cells are an underappreciated component of the tumor microenvironment that may promote tumor progression,” explained Charles N. Serhan, PhD, Director of the Center for Experimental Therapeutics and Reperfusion Injury at Brigham and Women's Hospital and Professor at Harvard Medical School. Serhan and colleagues therefore decided to investigate whether tumor cell debris can stimulate tumor growth.

What happens to water molecules in the light reactions
Pani-rosa [81]

Light reactions happens in the thylakoid membrane, and the calvin cycle happens in the stroma. What happens to water molecules in the light reactions? It's broken apart and the electrons go to photosystem II. ... Then they pump H+ into the thylakoids, and are used to make ATP out of ADP.

A researcher is studying how depression tends to be experienced by people of different ages. The researcher interviews depressed
navik [9.2K]

A researcher is studying how depression tends to be experienced by people of different ages. The researcher interviews depressed adolescents, young adults, individuals in their 30s and 50s, and those over 70 years old. The research design being used is called <u>cross-sectional</u>.

<u>Option: D</u>

<u>Explanation:</u>

A kind of design for observational study is understood as a cross-sectional framework. In a cross-sectional analysis the investigator simultaneously tests the participants in the study's result and exposures. Through cross sectional studies one can estimate the prevalence of disease.

A cross-sectional analysis, for instance, could be used to assess whether vulnerability to specific risk factors would correlate with specific outcomes. For illustration, a researcher may gather cross-sectional data about past smoking habits and current lung cancer diagnoses.

Select the best description of adaptations, below.
hram777 [196]

Answer: b

An inherited modification of structure or function that allows an organism to survive and reproduce in its environment.

Explanation:

Adaptation helps an organism to become better suited to survive and reproduce in its environment. It is change in an organism's structure or behavior.

Change in physical features of an organism is considered as structural adaptation. Example- fur in bear

Change in the way an organism does things to survive is called behavioral adaptation. Example- bird calls and migration from one place to another.

Adaptation is an essential feature that helps an organism to better servive in the environment. In case, an organism fails to adapt to changes in its environment, its immune system becomes weak and fails to work. This threatens its life and it becomes ill. This may also result in its death.
