Which component of the earth’s atmosphere is decreased due to photosynthesis?
ozone
oxygen
hydrogen peroxide
carbon dioxide
Answer:
Carbon Dioxide
Explanation:
Let's see the reaction of Photosynthesis
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Where carbon dioxide and water are reactants and glucose and oxygen are products which means CO₂ and H₂O are taken from the environment and glucose is supplied to plants while oxygen is supplied back to the environment.

If Jessica has light eyes (bb) and both of her
parents have dark eyes (Bb) which statement is
true?
A. Jessica inherited both genes from her father.
I
B.
Jessica inherited both genes from her mother,
C. Jessica inherited one recessive form of the
gene from each parent.
D.
Jessica inherited one dominant form of the
gene from each parent.
Answer:
D
Explanation:
Dominant and the recessive allele are the traits present in the genes that get inherited from the parent to their offspring.
The trait that is visible in the phenotype is called dominant while the trait that gets masked in the proximity of the dominant allele is called recessive.
The correct answer is:
Option C. Jessica inherited one recessive form of the gene from each parent.
This can be explained by :
The genotype of Jessica's eyes = bb (light)The genotype of her parents = Bb (dark eyes)See the attached image below for the cross:
The genes gets independently assorted and Jessica inherits the recessive form of the genes from both of her parent.
Therefore, Jessica inherited recessive gene one from each parent.

1. HYPOTHESIZE: Some human activities change environments in ways that harm both people and other
organisms. Describe one example of this kind of activity.
Answer:
Deforestation is one major human activity that harms both people and organisms. Cutting down trees lowers Earths ability to create fresh air, which leads to more toxic and polluted areas that can cause problems with breathing and even lead to lung cancer. Deforestation can harm other organisms because many animals such as birds, squirrels, and owls, look to the trees for a habitat. However, as we destroy they can cause a decrease in population which leads to an even bigger problem in the food chain.
Through the process photosynthesis, plants and algae transform
light energy into chemical energy. Where in the plant does
photosynthesis take place?
Answer:
Photosynthesis takes place inside the chloroplasts.
Explination:
Green plants use photosynthesis to create energy from carbon dioxide and sunlight. This energy, in the form of glucose, is used by the plant to grow. Photosynthesis occurs within these structures, which contain the substance chlorophyll.

How many chemical bonds can each carbon atom form?
Answer:
It has four valence electrons, which it can achieve a full outer energy level which forms four covalent bonds. When its bonds only with hydrogen, it forms compounds which is called hydrocarbons. Carbon can be form in single, double, or triple covalent bonds with other carbon atoms.
Explanation:
The valency of carbon is four. Therefore, carbon can form four chemical bonds.
What is a chemical bond?It is the attraction between two atoms, they share or exchange electrons to form molecules or compounds is known as a chemical bond. They share electrons to fulfill their valency. The number of bonds depends on the number of valencies.
There are three types of bonds and that are covalent, ionic, and metallic bond. A covalent bond or molecular bond is formed by sharing of electrons, it occurs in non-metals. Ionic bonds are formed by exchanging electrons, it occurs in both metal and non-metal. metallic bonds are present between two metals. The covalent bond is the strongest bond.
There are four valencies in carbon. Therefore, it can make four bonds.

Read the passage from Darwin's journal. sorry its so long
The Amblyrhynchus, a remarkable genus of , is confined to this archipelago; there are two species, resembling each other in general form, one being terrestrial and the other aquatic. This latter species (A. cristatus) was first characterized . . . from its short, broad head, and strong claws of equal length, that its habits of life would turn out very peculiar, and different from those of its nearest ally, the iguana. It is extremely common on all the islands throughout the group, and lives exclusively on the rocky sea-beaches, being never found . . . even ten yards in-shore. It is a hideous-looking creature of a dirty black colour, stupid, and sluggish in its movements. The usual length of a full-grown one is about a yard, but there are some even four feet long; a large one weighed twenty pounds: on the island of Albemarle, they seem to grow to a greater size than elsewhere. Their tails are flattened sideways, and all four feet partially webbed. They are occasionally seen some hundred yards from the shore, swimming about; and Captain Collnett, in his voyage says, “They go to sea in herds a-fishing, and sun themselves on the rocks; and may be called alligators in miniature.” It must not, however, be supposed that they live on fish. When in the water, this lizard swims with perfect ease and quickness, by a serpentine movement of its body and flattened tail—the legs being motionless and closely collapsed on its sides. A seaman on board sank one with a heavy weight attached to it, thinking thus to kill it directly, but when an hour afterwards, he drew up the line, it was quite active. Their limbs and strong claws are admirably adapted for crawling over the rugged and fissured masses of lava, which everywhere from the coast. In such situations, a group of six or seven of these hideous reptiles may oftentimes be seen on the black rocks, a few feet above the surf, basking in the sun with outstretched legs.
What structural adaptation does the A. cristatus lizard have to help them climb rocks?
Awnsers:
A.strong claws
B.black color
C.flattened tail
D.webbed feet
Answer:
A) strong claws
Explanation:
cause if they werent strong they would break if they tried to climb the rocks... also the first guy said webbed feet cause there is a VERY SIMILAR question that asked how they could swim... its in the screenshot of what he was answering
The structural adaptation does the cristatus lizard have to help them climb rocks is strong claws.
Explain your answer briefly?If they were not strong they would break if they tried to climb the rocks. Also the first guy said webbed feet cause there is a very similar question that asked how they could swim.

Why is it important to monitor the pH and other factors in the AgWorks lab
Answer:
To know the actual pH for a particular organism.
Explanation:
It should be understood that in a 6,100-square-foot lab and classroom named AgWorks, students not only learn how to grow food in a controlled environment, but also explore and have the idea of agriculture-related careers.
In this aspect, the monitoring of pH is very important because not all organism survive in acidic and basic mediums, but there are some that required neutral medium for their survival. And this is the reason why to always affirm the particular pH necessary for the survival of a particular organism.
