How does leaf structure allow for exchange of gases (O2 and CO2). Select 3 options.
Stomata (pores) let gases pass in and out.
Leaf is flat and thin = large surface area
The leaf has got Chloroplasts.
The Spongy Mesophyll layer has lots of space for gases to diffuse.
Answer:
Explanation:
Gas exchange
When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. It does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata. This movement of gases in opposite directions is called gas exchange.

The table below shows the percentages of bases in a DNA sample. How much Guanine (G) should you expect to find in the sample?
Answer:
17%
Explanation:
guanine is cooped
with cytosine
Using Chargaff's rule, the percentage of Guanine(G) in the sample is always equal to the percentage of Cytosine. Hence, the percentage of Guanine which is expected to be found in the sample ls 17%.
From the table attached :
Thymine = 33%Cytosine = 17%According to Chargaff ; the percentage of Cytosine equals the percentage of Guanine :
Guanine = Cytosine = 17%.
Percentage of Thymine equals the percentage of Adenine :
Adenine = Thymine = 33%Therefore, the amount of Guanine which is expected to be found in the sample is 17%

Answer:
The function of segregating the interior of the cell enclosure to the outside is known to occur by the function of the plasma membrane. These molecules comprising the plasma membrane is none other than lipids. Highly enriched hydrophobic tails of lipids interact with other lipids in a typical bilayer arrangement to regulate and control gene expressive Molecular and other crucial ions from moving in.

(PLS HELP DUE IN 5 MINS!) The pteropoda, or “sea butterfly”, is a tiny sea creature about the size of a small pea. Pteropoda are eaten by organisms ranging in size from tiny krill to whales. They are a major food source for the North Pacific juvenile. Their shells are made up of calcium carbonate. The photo provided is the shell of a pteropoda. The shell can dissolve within a 45 day period. What can one infer about what is causing the shell of the pteropoda to disappear while in a marine environment?
a) Carbon monoxide (CO) is being released by natural systems. Oceans are absorbing this excess of CO and the pH within the oceans is increasing.
b) Methane (CH4 is being released too quickly from burning of fossil fuels. Oceans are lowering their pH and ocean acidification occurs.
c) Natural sources are releasing an excess of CO2 to the oceans. The marine photosynthetic organisms are emitting too much oxygen. This is return is causing ocean acidification.
d) The excess of CO2 emitted from anthropogenic sources is being absorbed by the oceans from the atmosphere. This results in more hydrogen ions in the ocean, which increases acidification.
Answer:
The excess of CO2 emitted from anthropogenic sources is being absorbed by the oceans from the atmosphere. This results in more hydrogen ions in the ocean, which increases acidification.

A person with a genetic disease that codes for a specific protein could be 5 points
a candidate for which of the following?*
A. Cloning
B.gene therapy
C. DNA fingerprinting
D. Gel electrophoresis
A person with a genetic disease that codes for a specific protein could be a candidate for: B. gene therapy.
Genetics can be defined as the scientific study of hereditary and its components in an organism such as an animal, human, and plant.
Gene therapy can be defined as an experimental technique that involves the introduction of normal genetic materials into cells to produce a therapeutic effect that reconstructs or repair defective genetic materials, so as to treat a disease or cure genetic disorders.
Basically, gene therapy reconstructs or repair defective genetic materials found in body cells in an effort to treat or prevent a disease.
The three (3) main types of gene therapy are:
Gene inhibition therapy.Gene augmentation therapy.Killing of specific cells.In conclusion, an individual having a genetic disease that codes for a specific protein is most likely to be a candidate for gene therapy.

How do metamorphic rocks work?
Answer: Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. They are not made from molten rock. rocks that do melt form igneous rocks instead. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure.

Imagine that you are a scientist who has discovered a new object. You want to find out if the object is biotic or abiotic. You observe several characteristics about the new object. Which of these characteristics would tell you that the object is abiotic, or not alive?(1 point)
The object cannot create energy.
The object has a crystalline structure.
The object can mutate.
The object responds to stimuli.
Answer:
the answer is the object cannot create energy
Explanation:
i just got it right on my quick check
The characteristic that would tell if an object is abiotic or nonliving is if the object cannot create energy.
The capacity to create energy for the normal functioning of the body is one of the key characteristics of living organisms. This energy is usually gotten from the breakdown of food materials through a process known as respiration.
Respiration could be in the presence (aerobic) or absence (anaerobic) of oxygen but the ultimate end is to generate energy, usually in the form of ATP, for metabolism.
Thus, any object that lacks the capacity to carry out respiration cannot be considered to be living or biotic.
