Explanation:
A number that describes how likely it is that an event will occur is the _______ of the event.
Answer: The probability of an event is a number describing the chance that the event will happen. An event that is certain to happen has a probability of 1. An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1.
The number Which describes how likely it is that an event will occur is the probability of the event.
What is probability?The number describing a chance that an event will occur is called probability. It can be expressed in the form of numbers, from 0 and 1, or also by percentage from 0% to 100%. Higher probability of an event means that there are greater chances that event will occur.
Probability is branch of mathematics which is also applied in other fields such as, science, finance, statistics, gambling, computer science, machine learning, artificial intelligence and game theory.
Representation of probability in its formal terms, is called as probability theory. The probability theory is mostly used in risk assessment and modelling that is, it is used by insurance companies and markets.
Therefore, chances of number of event occur is called probability.

b. Oxygen is consumed.
c. Lactic acid is converted into pyruvic acid.
d. NAD+ is regenerated for use in glycolysis.
Answer:
D
Explanation:
Thats all i know hope it helps
Lactic acid is created when pyruvate is reduced to make it, while NAD+ is created when NADH is oxidized. Reducing pyruvate to lactate requires a proton from NADH and electrons from the molecule. Thus, option D is correct.
What is the role of Lactic acid fermentation?Anaerobic respiration occurs when human muscle cells do not receive enough oxygen. So, the fermentation of lactic acid results in the production of energy molecules. The result of this process is lactic acid.
Oxidize electron transporters to allow for glycolysis re-use. Without the aid of oxygen, fermentation enables cells to generate chemical energy from the breakdown of sugar, such as glucose.
Therefore, in lactic acid fermentation, NAD+ is regenerated for use in glycolysis.

1. are marsupials discussed to prove against biogeography/ geographic distribution. SHOW YOUR EXPLANATION!!
Answer:Marsupial mammals on Australia likely evolved from a common ancestor. ... Because Australia was isolated by water for millions of years, these species were able to evolve without competition from (or exchange with) mammal species elsewhere in the world.
Explanation:
Answer:
Biogeography is the study of the geographical distributions of biological organisms. For scientists who study evolution, biogeography is often an important part of their analysis, because it provides compelling proof for their theory. This is because many geographical features, such as oceans, rivers, mountains and islands, provide barriers to species, allowing scientists to observe how they evolve separately from one another.
Explanation:
PLS HELP! THANK YOU! :) explain the structure of plant organs and the adaptations plants have for pollination, fertilisation, dispersal, germination and plant growth
Explanation:
Introduction
Plants have evolved different reproductive strategies for the continuation of their species. Some plants reproduce sexually while others reproduce asexually, in contrast to animal species, which rely almost exclusively on sexual reproduction. Plant sexual reproduction usually depends on pollinating agents, while asexual reproduction is independent of these agents. Flowers are often the showiest or most strongly-scented part of plants. With their bright colors, fragrances, and interesting shapes and sizes, flowers attract insects, birds, and animals to serve their pollination needs. Other plants pollinate via wind or water; still others self-pollinate.
Asexual Reproduction
Vegetative reproduction is a type of asexual reproduction. Other terms that apply are vegetative propagation, clonal growth, or vegetative multiplication. Vegetative growth is enlargement of the individual plant, while vegetative reproduction is any process that results in new plant “individuals” without production of seeds or spores. It is both a natural process in many, many species as well as a process utilized or encouraged by horticulturists and farmers to obtain quantities of economically-valuable plants. In this respect, it is a form of cloning that has been carried out by humanity for thousands of years and by plants for hundreds of millions of years. Sexual Reproduction and The Flower
The flower is the reproductive organ of plants classified as angiosperms. All plants have the means and corresponding structures for reproducing sexually. The basic function of a flower is to produce seeds through sexual reproduction. Seeds are the next generation, serving as the primary method in most plants by which individuals of the species are dispersed across the landscape. Actual dispersal is, in most species, a function of the fruit (a structural part that typically surrounds the seed).
image
Plants and sexual reproduction: Plants that reproduce sexually often achieve fertilization with the help of pollinators such as (a) bees, (b) birds, and (c) butterflies.
Sexual Reproduction in Gymnosperms
Gymnosperms produce both male and female gametophytes on separate cones and rely on wind for pollination.
image
Male and female gametophytes: These series of micrographs shows male and female gymnosperm gametophytes. (a) This male cone, shown in cross section, has approximately 20 microsporophylls, each of which produces hundreds of male gametophytes (pollen grains). (b) Pollen grains are visible in this single microsporophyll. (c) This micrograph shows an individual pollen grain. (d) This cross section of a female cone shows portions of about 15 megasporophylls. (e) The ovule can be seen in this single megasporophyll. (f) Within this single ovule are the megaspore mother cell (MMC), micropyle, and a pollen grain.
Female Gametophyte
The female cone also has a central axis on which bracts known as megasporophylls are present. In the female cone, megaspore mother cells are present in the megasporangium. The megaspore mother cell divides by meiosis to produce four haploid megaspores. One of the megaspores divides to form the multicellular female gametophyte, while the others divide to form the rest of the structure. The female gametophyte is contained within a structure called the archegonium.
Reproductive Process
Upon landing on the female cone, the tube cell of the pollen forms the pollen tube, through which the generative cell migrates towards the female gametophyte through the micropyle. It takes approximately one year for the pollen tube to grow and migrate towards the female gametophyte. The male gametophyte containing the generative cell splits into two sperm nuclei, one of which fuses with the egg, while the other degenerates. After fertilization of the egg, the diploid zygote is formed, which divides by mitosis to form the embryo. The scales of the cones are closed during development of the seed. The seed is covered by a seed coat, which is derived from the female sporophyte. Seed development takes another one to two years. Once the seed is ready to be dispersed, the bracts of the female cones open to allow the dispersal of seed; no fruit formation takes place because gymnosperm seeds have no covering.

Why did Mendel study pea plants?
Answer:
Pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow and could be bred rapidly and had many several observable characteristics like petal color and pea color. Mendel used a tall plant and a small plant expecting a medium plant to com out. That was not the case one tall plant came out and so did 3 small ones. This is because of genetics.

You overhear Kali describing her trip to the ocean to a friend. She explains that she waded out onto the continental rise, but was careful not to go too far, because she didn’t want to reach the steep decline of the continental slope. What part of her story needs to be corrected?
A. She needed to be careful of the continental shelf, not the slope.
B. She was on the continental shelf, not the continental rise.
C. She was on the continental slope and needed to be careful of the rise.
D. Continental slopes are not steep declines, they are gradual.
Answer:
B. She was on the continental shelf, not the continental rise.
Explanation:
The continent first contacts the ocean at the continental shelf. After a while, the continental shelf ends in a steep decline known as the continental slope. The continental slope eventually levels out into a gradually sloping continental rise which eventually becomes the ocean floor.
The part of her story that needs to be corrected is that she was on the continental shelf, not the continental rise. The correct option is B.
What is continental shelf?A continental shelf is a portion of a continent that is submerged beneath a shallow body of water known as a shelf sea.
During glacial periods, sea level drops exposed many of these shelves. The shelf surrounding an island is known as an insular shelf.
The continental shelf is where the continent first makes contact with the ocean. The continental shelf eventually ends in a steep decline recognized as the continental slope.
The continental slope eventually flattens out and becomes a gradually sloping continental rise, which eventually becomes the ocean floor.
Her story needs to be corrected because she was on the continental shelf, not the continental rise.
Thus, the correct option is B.
