why blood is classified as tissue in cellular organization?
Answer:
Blood is considered as a connective tissue .
Connective tissues have cells scattered throughout an extracellular matrix. They connect different body systems. Blood is considered as a type of connective tissue because of two reasons.
(i) Like the other connective tissues, blood is mesodermal in origin.
(ii) It connects the body systems, transports oxygen and nutrients to all the parts of the body, and removes the waste products. Blood has an extra-cellular matrix called plasma, with red blood cells, white blood cells, and platelets floating in it.

Explanation:
In the ATP Cycle energy is transferred from sunlight or glucose to build _____ from ADP and _____________.
Answer:
1. ATP
2. Inorganic phosphate (Pi)
Explanation:
Adenosine triphosphate (ATP) is the usable form of energy by the cells of living organisms. During the light reaction of photosynthesis, energy from sunlight (solar energy) is converted to ATP in order to power the Calvin cycle stage. Also during cellular respiration, energy stored in glucose molecule is transferred to ATP.
The processes by which this synthesis of ATP from ADP (Adenosine diphosphate) occurs is called oxidative phosphorylation and chemiosmosis. Energy is stored in the ATP molecule when ADP combines with inorganic phosphate (Pi).

"The beaks of the Galapagos finches that Darwin observed evolved into multiple shapes, and each is adapted for what?"
Answer:
Finch beaks were differentiated according to the different foods that each particular finch fed on.
Each finch developed in different zones and climax of the Galapagos island, that is why they were conditioned by the environment in which they lived, each particular environment made these finches adapt and evolve to be able to fulfill their life and not with extinction of the species.
This speaks of the evolution of species, how it adapted to environmental changes to survive, and how the fittest survive in the face of adversity.
Explanation:
Animals can have genetic modifications, which if they are inherited through generations and are optimal for the species is considered evolutionary processes of the species, beneficial for its survival.
Genetic changes are stimulated by environmental changes, and expressed with phenotypes, that is, with physical characteristics or qualities such as the different morphologies of finch beaks.
Each finch feeds on different sources, that is why those that eat hard insects will have more resistant beaks, those that have to remove the insect from the trees have more pointed beaks, those that grind seeds or fruits from the ground have more robust beaks and in the form of a "hook" for the possible crushing of the husk of the seed.
Can star positions be used to determine the future
Answer:
Since stars basically move freely through space, we can use their proper motions to predict where they will be in the future. A star can also move toward us or away from us, following what is known as radial motion. The combination of radial motion and proper motion determines a star's true motion relative to us.

Which of the following best describe(s) the function of the 5' mRNA cap?
a) Termination of transcription
b) To provide a binding site for poly(A) polymerase
c) It provides a site for ribosome binding in the cytoplasm
d) To protect the transcript from degradation
Answer:
c) It provides a site for ribosome binding in the cytoplasm
d) To protect the transcript from degradation
Explanation:
Transcription is the very first stage of gene expression, which involves the synthesis of a mRNA molecule from a DNA template. The mRNA transcript produced is referred to as a pre-mRNA until it undergoes further processing in the nucleus. This processing makes it matured and ready to be translated (form protein).
The mRNA processing involves three main processes viz: 5' capping, 3' polyadenylation and splicing. The capping of the 5' of the mRNA involves the addition of a 7-methyl guanosine molecule to the 5' of the mRNA molecule. This capping helps protect the mRNA transcript from being degraded by nucleases (digestive enzymes in the nucleus). In addition to this function, the added CAP also provides a recognition site for ribosome to bind to during translation initiation.

What is NOT a function of the endocrine system? Select one: a. Production of white blood cells b. Influencing fluid absorption c. Assisting with sperm production d. Influencing body’s energy level and metabolism
Answer:
Option a. Production of white blood cells
Explanation:
The endocrine system is the system that involves the organs and glands that produce and secretes the hormones that acts on various other activity to regulate responses or activity.
Major function and examples of endocrine system are :
Aldosterone helps in fluid absorption in kidney
Thyroxine helps in regulating body metabolism and energy
Testosterone is responsible for sperm production is regulated
But, WBC formation is not regulated by hormones.
Thus, the correct answer is: option a. Production of white blood cells

Energy receipt is highest between 0° and 23.5° N and S as this is where the sun moves overhead. What would happen if instead the sun moved overhead across a much larger region, such that it was traveling overhead between 0° and 60° N and S? Think about how think might impact certain, major wind patterns.
Answer:
Energy receipt is most noteworthy between the tropics. Had the sun gone up to 60 N and S and back forward, this would have prompted total decimation in significant wind pattern, numerous biomes, for example, Mediterranean biome.
Be that as it may, the most vital effect would have been on the wind patterns since worldwide wind pattern (mainly first order wind) are to a great extent reliant on the weight belt which are constantly influenced by the development of the sun to and fro.
Taking into account that Sun begins its excursion up to 60 N and S, at that point for a day, the Sun would be overhead on this scope. This would imply that during summer solstice (in northern half of the globe), all the weight belts and likewise wind belts would be reached out up to the 60. Thus, the proportionate region under the exchange winds that streams between the equator and the sub-tropical high-pressure belt would increment and the locale under Westerlies effect would additionally build toward the north.
What prevents organisms from reproducing an unlimited number of offspring?
The primary reason living organisms cannot produce an unlimited number of offspring is senescence, otherwise known as old age.
Cells of the reproductive organs divide and continually make it possible for organisms to reproduce. As time goes on, the old cell dies and new cells replace them through mitotic or meiotic cell division of young cells that still has the ability to divide.
However, as programmed cell deaths occur with old age, the reproductive cells start losing the ability to divide, and when this happens, the ability for organisms to reproduce becomes limited.

One of the most crucial factors in the development of fatigue appears to be a depletion of ATP.
a. True
b. False
Answer:
Option A
True
Explanation:
Adenosine triphosphate (ATP) is the molecule in the cells that carry energy. They help to trap the energy that is obtained during respiration and the breaking down of food, in order to release it to the cells of the living organisms when the need arises.
Once the ATP levels deplete in the body, cellular fatigue begins to occur, as the cells do not have the required energy to perform their necessary functions.
This makes the correct option to be A: True. The depletion of the ATP levels in the body causes fatigue
