Answer:golgi apparatus
Explanation:
Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen? A. The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle. B. The energy flow—and thus oxygen flow—for cellular respiration and photosynthesis take place in the same direction, and therefore build upon one another. C. Cellular respiration is a process that releases energy and oxygen, while photosynthesis withdraws energy and uses oxygen, therefore keeping each process in balance. D. Oxygen readily accepts electrons, so cellular respiration uses a negligible amount of oxygen.

What controls when a cell divides?
Answer:
A variety of genes are involved in the control of cell growth and division. Tight regulation of this process ensures that a dividing cell's DNA is copied properly, any errors in the DNA are repaired, and each daughter cell receives a full set of chromosomes.

What do you notice about the Moon’s orbit?
Answer:The Moon has a nearly circular orbit (e=0.05) which is tilted about 5° to the plane of the Earth's orbit. Its average distance from the Earth is 384,400 km. ... Therefore, Earth-bound observers can never see the 'far-side' of the Moon. Tidal forces cause many of the moons of our solar system to have this type of orbit.

Binomial Nomenclature
Explanation:
Karl Line is the creator of the binomial nomenclature, which leads to uniqueness in naming plants and categorizing plants into classes, orders, genders, and species.
Binomial nomenclature in biology denotes the official method of naming species. As the word itself suggests, the scientific name is formed by a combination of two expressions: the name of a genus and a species.

One difference between weather and climate is that _____. climate is localized, and weather occurs over large areas. weather is localized, and climate occurs over large areas. weather is the day-to-day conditions, and climate is the conditions expected over relatively long periods of time. climate is the day-to-day conditions, and weather is the conditions expected over relatively long periods of time.
Answer:
Weather is the day-to-day conditions, and climate is the conditions expected over relatively long periods of time.
Explanation:
The difference between weather and climate is how long the period of time they refer to is.
Weather is what conditions of the atmosphere are over a short period of time, or day-to-day conditions. It's what we see on the weather forecast every day - whether it's going to be sunny or rainy today and tomorrow and similar.
Climate is what conditions of the atmosphere are over longer periods of time, usually 30 years. In fact, it's an average pattern of weather for a particular region. A description of a region's climate will include the precipitation, temperature, humidity, sunshine, wind velocity, phenomena such as fog, frost, and hail storms, and similar conditions.

4. When an offspring grows off from the body of a parent organism it is called __________________. *
a.fission
b.budding
c.fragmentation
d.sporulatioin
Answer:
Budding
Explanation:
It is asexual reproduction in which offspring grows out of the parents organisms.
In the process of budding, an offspring grows off from the body of a parent organism and buds off when fully matured. Thus, the correct option is B.
What is Asexual Reproduction?
Asexual reproduction is the type of reproduction only a single parent is involved. In this process, offspring are developed from a single parent called mother cell and these offspring are genetically identical to the parent hence are also called as clones.
During the process of budding which is a types of asexual reproduction, a new organism develops from an outgrowth or bud which is formed on the parent plant due to the cell division at a particular site on the parent plant. For example, the small bulb-like projections coming out from the yeast cell are the buds which give rise to new yeast organism.
Therefore, the correct option is B.

What is a major difference between DNA replication and DNA transcription?
Answer:
RNA molecules produced by transcription are much shorter in length than DNA molecules produced by replication.
Explanation:
In DNA transcription, only a segment of DNA is copied, or "transcribed," to a complementary strand of messenger RNA.
In DNA replication, the entire length of the DNA molecule is copied so that it can be passed to a new cell.

Which statement describes competition in an environment? Organisms share a place to sleep. A living thing consumes berries on a tree. Sunlight shines only three months out of the year. A stream supplies an abundance of water in a forest.
Answer:
Sunlight shines only three months out of the year.
Explanation:
I think this is right
Because abundance means a large amount so there would be no competition there.
If organisms share a place to sleep then that means no competition
If a living thing is consuming berries on a tree then the living thing is just eating
But if the sunlight only shines three months out of the year then that can cause a shortage of food in the environment causing for the living creatures in the environment to compete for the food that is left since there won't be enough to supply for and abundance of living things.
The statement that describes competition in an environment is option B a living thing consumes berries on a tree. Thus, consuming berries on a tree is reducing the availability of the food for other livings depends on the berries.
What is survival of living things?In the nature, the concept that survival of the fittest domintates. The organisms which are fit physically and are smart to gather food will survive in the nature otherwise they will extincts.
An ecological community is a collection of populations of at least two distinct species that interact both directly and indirectly in a specific geographic area. Within this community, diffrent organisms can be found .
Numerous ecological characteristics and functions, including nutrient cycling and food webs, are based on interactions between species. Depending on the evolutionary context and environmental factors that they take place in, these interactions can have a variety of different natures.
Because of this, ecological interactions between particular individuals and entire species are frequently difficult to identify and quantify and depend on their scale and context they face extinction. Hence, option B is correct.

An mRNA cap will be found on ____________.
a. the primary transcript
b. the mRNA
c. at least one of the lariats
d. the poly(A) tail.
e. exon 1
f. all exons
g. some introns
Answer:
a. the primary transcript
Explanation:
The first step in RNAm maturation is the modification of the 5' end of the transcript via the addition of a structure called a cap or 7-methyl guanosine cap. The enzymes responsible for the formation of this cap are recruited to the phosphorylated C-terminal domain after the addition of the first twenty to thirty nucleotides of ARN. The formation of the cap is started by the addition of a GTP molecule oriented inversely to the 5' end nucleotide on RNA. Then methyl groups are added to this G residue and to the ribose forms of one or two nucleotides located on the 5' end. All these reactions take place in the nucleus when the mRNA is found as a primary transcript.

Answer:
According to the image, the approximate QT interval is 0.4 seconds.
Explanation:
The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.
Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.
In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:
0.04 seconds X 10 mm = 0.4 seconds.
Then, the estimated QT interval is 0.4 seconds.
