Answer:
1. --> d. Species diversity
2. --> a. Genetic diversity
3. --> a. Controlling pests, b. Providing medically useful chemicals , and c. Keeping topsoil fertile
Explanation:
1) Kinds of biodiversity
Genetic diversity: Among species. Refers to genes variability among species that differentiate them and allows them to adapt to different environments. The genetic charge of one species differs from other species´ genetic charge. Species diversity: Refers to the diversity of species, which can be measured by: Species richness: Number of species in a defined unit sample, Species abundance: Describe the distribution of the species abundance.Species richness is the number of species present in a sample, within a community, habitat or microhabitat, ecosystem, landscape, region, or any well-defined spatial unit. It is simple and easy to interpret. It is the simplest and straightforward measure of biodiversity. It is just a count of species, with no need for abundance data. In some cases, this can be the cause of criticism, as it ignores information about the species-abundance distribution.
2) Ecosystem services
When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear fresh-water, fertile soils, geotic materials, raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.
Regulation:Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.
Cultural:Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, to learn, provides a spiritual/religious space, is a source of inspiration, it is considered to be cultural patrimony, and the source of scientific knowledge.

Answer:
Yes, All of the cells divide at approximately the same rate, although they may divide at different times
Those organisms which are made up of more than one cell are called multicellular organisms.
These are a few examples of multicellular organisms:-
PlantsAnimalsFungiMulticellularity helps them to perform various work at the same time. To maintain the same number of cells in an organism, its body starts cell division.
It is not necessary for the host to divide all the cells at the same time.
Hence the correct option is Yes. All of the cells divide at approximately the same rate, although they may divide at different times.

What are the structural differences between a cockroach and a grasshopper?
Cockroaches have legs for crawling on walls and ceilings, but grasshoppers have legs for jumping. Some cockroaches have wings for flying, but most others don't. Grasshoppers have wings for making a sound, whether it's to attract a mate or to just be annoying. Grasshoppers have a body that is split into multiple segments (more than just one), while cockroaches have only like 2 body segments. Cockroaches have barbs on their legs for a sense of touch, while grasshoppers don't. The legs of a cockroach are very sensitive though. Cockroaches can survive a nuclear explosions because the rads don't affect them. But the heat from the nuclear blast will certainly kill a human, as well as a cockroach if exposed. Obviously, grasshoppers couldn't survive a nuclear explosion. The only down side to roaches surviving a nuclear explosion is them turning into radroaches, like in the Fallout game series from the game developing company, Bethesda Game Studios! If there were a nuclear explosion, then the roaches would mutate into human head sized roaches that can actually attack a human! (this is just a theory, not scientifically proven, lol)

HELP I NEED A NUMBER OUT OF 16
Answer:
9/16
Explanation:
RrYy x 2
Answer:
9 out of 16 (also 9/16)
Explanation:
Count the likeliness of the offspring to be round:
RR, Rr, rR, rr
round shape is 3 out of 4 times
Count the likeliness of the offspring to be yellow:
YY, Yy, yY, yy
yellow color is 3 out of 4 times
Multiply the likeliness of being round and being yellow (since they are two independent probabilities, we are using multiplication rule):
3/4 * 3/4 = 9/16

The genotype and phenotype of the pea plant - pp - white flower
According to Mendel, there are two or more alleles (normally two) are responsible for the expression of a trait encoded by the gene.
One allele of the particular gene has the ability to mask the phenotypic expression of the other if present in a genotype together.The allele that masks another is called the dominant allele while the allele being masked is the recessive allele.The recessive allele express their effect only if they are present with the same allele in the genotypeIn this case, a gene that codes for flower color in pea plants is involved.The purple allele (P) is dominant over the white allele (p).It is given that the pea plant has white flower color that is a recessive allele therefore, it is clear that it has two recessive alleles p in its genotype.Thus, the genotype and phenotype of the pea plant - pp - white flower

A researcher in 2024 studies the evolutionary relationships between influenza viruses by comparing the genomic sequences of the viruses found in pigs, ducks, and humans in a given year. When evaluating the viruses that had infected these hosts the previous year, she identifies a cross-species transfer from pigs to ducks in the year 2022. What information supports the hypothesis that cross-species transfer leads to more severe disease in the new host
Answer:
pigs suffered severe influenza in the year 2022
Explanation:
Influenza, commonly known as flu, is a viral infectious disease caused by different types of influenza viruses. Some of the most common symptoms of this disease include, among others, headache, coughing, fever, muscle pain, etc. Influenza viruses can affect humans and different animals such as, for example, cats, dogs, birds and horses. There is evidence showing cross-species influenza virus transmission. For example, it has been shown that the influenza type A virus can be transmitted from one species to another (for example, between humans and pigs). In these cases, cross-species transmission information may indicate how much potential a virus has to cause a pandemic in the new host by analyzing the severity and infectivity of the virus in the original host.

A variety of opium poppy (Papaver somniferum L.) having lacerated leaves was crossed with a variety that has normal leaves. All the F1 had lacerated leaves. Two F1 plants were interbred to produce the F2. Of the F2, 249 had lacerated leaves and 16 had normal leaves. Give genotypes for all the plants in the F1, and F2 generations. Explain how lacerate leaves are determined in the opium poppy. (Section 5.2)
Answer:
The correct answer is-
F1 - AaBb (lacerate)
F2 - A_B_; A_bb; and aaB_ (lacerate)
- aabb (normal)
2. Two genes, with a dominant allele at either or both loci.
Explanation:
The given information gives THE following data:
Dominant: Lancerate leaves - AABB
Recessive: normal leaves - aabb
F1 has - all Lacerated leaves - AaBb
F2 by selfing F1:
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb Aabb aaBb aabb
Here, 15/16 = lacerate which is 0.94 which is equal to the value of lacerate given in the question - 249/265 = 0.94
And normal 1/16 = 0.062 is almost same as 16/265 = 0.060
Thus, the genotypes of -
F1 - AaBb (lacerate)
F2 - A_B_; A_bb; and aaB_ (lacerate)
- aabb (normal)

Describe the difference between gene mutations and chromosomal mutations, including:
- What are they?
- How do they occur, including their types?
- When will they result in a change in the phenotype of offspring?
Explanation:
Genetic alternations include chromosomal abnormalities and gene mutations. Chromosomal abnormalities generally arise during cell division. ... Gene mutations are permanent changes in DNA gene sequence. They can arise during normal DNA replication or in response to environmental factors.
Answer:
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.
What type of mutation can affect offspring?
The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. No change occurs in phenotype. Some mutations don't have any noticeable effect on the phenotype of an organism.

Explanation:
You are trying to find which wavelength of light would allow algae to do photosynthesis the worst (you want to prevent algal growth in your pond). Describe your experiment setup:
hypothesis (1 point)
independent variable (1 point - you can choose anything)
dependent variable (1 point) and how you will measure the dependent variable (1 point)
variables you will keep constant (1 point)
Answer:
The light reactions of many algae differ from those of land plants because some of them use different pigments to harvest light. Chlorophylls absorb primarily blue and red light, whereas carotenoids absorb primarily blue and green light, and phycobiliproteins absorb primarily blue or red light. Since the amount of light absorbed depends upon the pigment composition and concentration found in the alga, some algae absorb more light at a given wavelength, and therefore, potentially, those algae can convert more light energy of that wavelength to chemical energy via photosynthesis. All algae use chlorophyll a to collect photosynthetically active light. Green algae and euglenophytes also use chlorophyll b. In addition to chlorophyll a, the remaining algae also use various combinations of other chlorophylls, chlorophyllides, carotenoids, and phycobiliproteins to collect additional light from wavelengths of the spectrum not absorbed by chlorophyll a or b. The chromophyte algae, dinoflagellates, cryptomonads (class Cryptophyceae), and the class Micromonadophyceae, for example, also use chlorophyllides. (Chlorophyllides, often incorrectly called chlorophylls, differ from true chlorophylls in that they lack the long, fat-soluble phytol tail that is characteristic of chlorophylls.) Some green algae use carotenoids for harvesting photosynthetically active light, but the Dinophyceae and chromophyte algae almost always use carotenoids. Phycobiliproteins, which appear either blue (phycocyanins) or red (phycoerythrins), are found in red algae and cryptomonads.
