Oxygen released during photosynthesis comes from
A. ATP
B.H2O
C.CO2
D.C6H12O6
Answer:
B. H2O
Explanation:
Answer:
I believe it is D.
Explanation:
Through chemical reactions, leaves use the carbon and the hydrogen and form a carbohydrate (C₆H₁₂O₆). The extra oxygen is released as a byproduct. This is the oxygen that we use when we breathe.
Losing 100 orangutans a week is an astonishing number. Within your lifetime they could become extinct in the wild because of human impact. We use palm sugar in many products consumed and other things. Do you feel that it could be said we have a parasitic relationship with orangutans? Defend your answer.
Answer:
if the orangutans eat the fruits, basically their place of residence is their only means obtaining food and if the human continues to cut trees and destroy forests, the fruits will be lost and the monkeys will starve and thus could become extinct.
Explanation:

Environmental agencies throughout the world believe that humans have forced Earth out of its natural cycle. Consider the choices below as possible sources of empirical evidence for anthropogenic climate change. Which choice does not support this view?
Answer:
Human activities increases the concentration of oxygen in the atmosphere.
Explanation:
Human is not responsible for the balance of oxygen gas in the atmosphere because human takes oxygen from the environment for the production of energy in the process of respiration. Plants are the key factor for maintaining the oxygen concentration in the atmosphere. Human activities are the main reason of increasing carbon-dioxide and other harmful gases in the atmosphere and increases the air pollution and change in climate occurs.

How does disease affect blood pressure
Explanation:
The body has lots of mechanisms that can control the blood pressure, plus, changing the amount of blood the heart pumps, the diameter of the arteries, and volume of blood in the bloodstream. When a disease causes blood pressure to stay high, low, or in between, problems can arise.

Brandy knows that chromosomes behave differently in meiosis and mitosis. What do chromosomes do in meiosis but not in mitosis?
Each chromosome makes a copy.
The homologous chromosomes form pairs.
Chromosomes line up in the middle of the cell.
Chromosomes condense or shorten up before cell division begins.
Answer:
It's B
Explanation:
"The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
Answer:
The homologous chromosomes form pairs.
Explanation:
Match each organ or function with its body system.
produces urine
large intestine
ureters
mouth
filters blood
absorbs nutrients
from food
Excretory
Digestive
Answer: Produces Urine- Excretory
Large intestine- Digestive
Ureters- Excretory
Mouth- Digestive
Filters blood- Excretory
Absorbs Nutrients- Digestive
The organs can be matched as Excretory system: produces urine, have ureters, filters blood. Digestive system: have large intestine, mouth and absorbs nutrients from food.
What is body system?An organ system is a biological system made up of a collection of organs that collaborate to perform one or more functions.
Each organ in a plant or animal body serves a specific function and is made up of distinct tissues.
The excretory system is a passive biological system that removes excess, unnecessary materials from an organism's body fluids to help maintain internal chemical homeostasis and prevent body damage.
The gastrointestinal tract, as well as the digestive organs, comprise the human digestive system.
Digestion is the process of breaking down food into smaller and smaller components so that it can be absorbed and assimilated by the body.
Thus, excretory system is related to urine production, have ureters, blood filtration, while digestive system includes large intestine, mouth and absorbs nutrients from food.

How does the Classification system distinguish between organisms?
Answer:
By organising them into five major kingdoms and further dividing each kingdom into phyla (or divisions), classes, orders, families, genus, and species.
Explanation:
There are five kingdoms:
Monera: bacteria Protista: amoeba, paramecium, euglenaFungi: yeast, rhizopusPlantae: flowering and non-flowering plantsAnimalia: animals (vertebrates and invertebrates)Organisms that share the most similar features are grouped into the same species. Species with similar features fall under the same genus. Several genus make up a family, several families make up an order, several orders make up a class, several classes make up a phylum (or division), and several phyla (or divisions) make up a kingdom.
Note: there are three domains (or superkingdoms): Archea, Bacteria, and Eukarya.

B. It decreases speed.
C. It changes its overall direction.
D. It moves in the same direction.

When a ball is thrown everyone of these things happen except for C because when you throw a ball it does not just turn and come back to you, it falls to the ground after going some distance.
How can a mutation that causes a change in the structure or function of a protein be beneficial to an organism?
Answer:
The development and function of an organism is in large part controlled by genes. Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression.
Explanation:
Mutations can result in structural alterations in a gene's translation, as well as a decrease or complete loss of the gene's function.
Because a change in the DNA sequence affects all copies of the encoded protein, mutations may be extremely detrimental to a cell or organism.
Genes have a crucial part in an organism's development and function. Mutations can result in structural changes in the decoding of a gene, as well as a decrease or complete loss of its activity.

A skateboard manufacturing company has had problems with the wheels on its skateboards cracking and causing injuries. An engineer for the company knows of a material that he thinks will make the skateboards safer. What would be the best step for the engineer to take next?
He should publish a report about the innovation and its impact on public safety.
He should conduct tests using computer models to determine the safety impact.
He should immediately begin producing all skateboards with the new material.
He should convert production of half of the skateboards to use the new material.
Answer:
Option B, He should conduct tests using computer models to determine the safety impact.
Explanation:
The better performance of material proposed by engineer will be treated as a claim without any proof, if the production of the stake board starts without testing it.
In order to verify his/her statement, the engineer needs to conduct durability and strength test on stake board having the “proposed material” in its structure.
After the test results are obtained, they must be vetted through publication as research paper.
Hence, option B is correct

A) 8
B) 16
C) 32
D) 64
B
Explain how the random alignment of homologous chromosomes during metaphase I contributes to variation in gametes produced by meiosis.
Random alignment leads to new combinations of traits. The chromosomes that were originally inherited by the gamete-producing individual came equally from the egg and the sperm. In metaphase I, the duplicated copies of these maternal and paternal homologous chromosomes line up across the center of the cell to form a tetrad. The orientation of each tetrad is random. There is an equal chance that the maternally derived chromosomes will be facing either pole. The same is true of the paternally derived chromosomes. The alignment should occur differently in almost every meiosis. As the homologous chromosomes are pulled apart in anaphase I, any combination of maternal and paternal chromosomes will move toward each pole. The gametes formed from these two groups of chromosomes will have a mixture of traits from the individual’s parents. Each gamete is unique.
In what ways is meiosis II similar to and different from mitosis of a diploid cell?
The two divisions are similar in that the chromosomes line up along the metaphase plate individually, meaning unpaired with other chromosomes (as in meiosis I). In addition, each chromosome consists of two sister chromatids that will be pulled apart. The two divisions are different because in meiosis II there are half the number of chromosomes that are present in a diploid cell of the same species undergoing mitosis. This is because meiosis I reduced the number of chromosomes to a haploid state.
