Answer:
A
Explanation:
because it is known as a large molecule
The starch molecule is known as a good source of energy for an organism because the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.
What is a Starch molecule?A starch molecule may be defined as a type of molecule that significantly consists of a chain of glucose molecules that are bound together in order to construct a bigger molecule, which is called a polysaccharide.
There are two types of polysaccharides present in the molecules of starch. They are as follows:
Amylose: It is a linear chain of glucose. Amylopectin: It is highly a branched chain of glucose.These long chains of glucose store a tremendous amount of energy during the synthesis of the starch molecules. Glucose provides instant energy while the breakdown of bonds in starch molecules takes time. So, the energy is liberated accordingly with a long-lasting effect.
Therefore, the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.

Answer: The options are not given, here are the options.
a. located in the space outside the nucleus.
b. spread evenly throughout an atom. c. concentrated at multiple sites in an atom.
d. concentrated in the center of an atom.
The correct option is D.
concentrated in the center of an atom.
Explanation:
In an atomic model, the atomic particles has the nucleus which is located at the center of the particle. This nucleus contain positive charge which is called proton at the center and the neutrons(no charge). The electrons is located out side the particle she'll or nucleus and atomic particles become neutral because the number of protons is equal to the number of electrons which is negatively charge orbiting outside the nucleus.

Question 2 (1 point)
Answer:
it would be (d) amount of pressure in the air caused by gravity and matter moving on all objects
Explanation:
d. amount of pressure in the air caused by gravity and matter moving on all objects.
Air pressure:The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. As the pressure decreases, the amount of oxygen available to breathe also decreases. Atmospheric pressure is an indicator of weather.Thus, the correct statement that describes air pressure is the amount of pressure in the air caused by gravity and matter moving on all objects i.e. option d.

A radioactive substance has a half-life of 1.25 million years. What is the age of a rock in which 6.25% of the original radioactive atoms remain? 5 million years old 6.25 million years old 3.75 million years old6 2.5 million years old 1.25 million years old 625 thousand years old
Answer:
The age of the rock is 5 million years
Explanation:
Fraction of radioactive substance remaining = 6.25% = 625/10000 = 1/16
Number of half-lives undergone by the substance to leave behind 1/16 of the original sample
1/16 = (1/2) * (1/2) * (1/2) *(1/2)
Therefore, the substance have decayed 4 times
One half=life = 1.25 million years
Four half-lives = 4 * 1.25 million years = 5 million years
Therefore, the age of the rock is 5 million years

Answer:
Pig
Explanation:
Pig valves are already used successfully in heart transplants. Human-to-human organ transplantation has only been around since the 1950s, and scientists have been working on animal-to-human transplants for almost that long. In the '60s, Keith Reemtsma experimented with transplanting chimpanzee kidneys into humans.
Answer:

Explanation:
This process is called Xenotransplantation. The animal organ, probably from a pig or baboon could be genetically altered with human genes to trick a patient's immune system into accepting it as a part of its own body. (Wikipedia)

с C
The cells would have remained the same as the freshwater is isotonic.
D
The cells would have become freshwater cells until reaching the ocean.
Answer:

After the 2004 tsunami disaster in Asia, there were reports that trained elephants had moved away
from the coastline before the tsunami struck. Scientists wondered if elephants had sensed the oncoming wave and the earthquake that created it. Elephant trunks have two kinds of nerve endings that are sensitive to pressure differences, but little is known about nerve ending distribution in the elephant's skin or feet. An elephant has recently died at a nearby zoo and scientists have decided
to dissect one of its feet to search for any special nerve endings. Results show a high density of pressure-sensitive nerve endings in the front of the foot and along the edges, which supports the
idea that elephants are sensing seismic signals produced by such disasters as earthquakes.
1. Independent variable
2. Dependent variable
4. Constant
5.controls
6.hypothesis
7. Sample size
8. Presence of repeated measures
Answer:
In the given dissection for the finding of the idea that elephant can sense the seismic signals generated by natural disasters are as follows:
Independent variable: it is the variable which influences the dependent variable or the dependent variable depends on. Here the area of the feet that is chosen to be dissected is the independent variable.
Dependent variable: It is the variable that is manipulated or influenced by the independent variable, in this dissection the sensitive to the pressure, nerve ending in the selected area of the feet.
Constants: It is a variable that remains constant or fixed in the complete experiment. The number of the selection area is constant hat is in one foot here.
Controls: There is no such control present in this experiment However, the density of pressure-sensitive nerve endings can be considered as control.
Hypothesis: the pressure-sensitive ending is significantly enriched in the feet of the elephant.
Sample size: subject in this study is only one elephant and one foot so the sample size is 1.
Presence of repeated measures: Repeated measures are not performed during this study is only one experiment of dissection is performed on a single subject.
Are humans heterotrophs or autotrophs? Pleas Help Me.. Thx:)
Answer:
Heterotroph
Explanation:
They require other sources to sustain themselves and cannot produce their own energy.
Answer:
Heterotrophs
Explanation:
Producers are the most common type of autotrophs because they are able to make food out of energy and any other materials they happen to find or lie upon. Humans cannot create food from energy because they are not producers.
Heterotrophs are organisms that eat consumers or producers. A human can eat other consumers (meat/omnivore) and eat plants (producer) like lettuce or kale.
Best of Luck!
