The reasons why the ocean marine biomes are a challenging place for organisms to live are :
All of the organisms have to live without sunlight ( B ) Organisms have to be able to live in extremely salty conditions ( D ) Marine BiomesThe marine Biomes consists of coral reefs, oceans and estuaries and marine algaes which provides the most of the oxygen needed in the world. Ocean marine biomes are salty and organisms living in such biomes have to live in extremely salty conditions.
Sunlight does not easily penetrate the Ocean marine Biomes due to the depth therefore the organisms must live without sunlight for most of their lifetime.
Hence we can conclude that The reasons why the ocean marine biomes are a challenging place for organisms to live are :

A freckled man marries a woman without freckles. They have four children, two with freckles, and two without freckles. What are the genotypes of all these people?
Answer:
The genotype of the father: Ff
The genotype of the mother: ff
The genotype of the two children without freckles: ff
The genotype of the two children with freckles: Ff
Explanation:
Freckles (F) are is dominant trait, so one dominant allele in the genotype of an individual will cause he/she to have freckles. Since the father has freckles, but only two of his children has freckles; that means that he has a heterozygous genotype. In the Punnett Square, the offsprings' genotypes are shown, as well as the parents'.
A freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.
What is the significance of the freckle trait?There are both dominant and recessive traits that determine the person's quality, such as freckles, which are dominant over being freckleless. When the parents with freckles cross with the parents without freckles, they will produce half the freckles and half the freckleless. The parent with a freckle is heterozygous (Ff), so two types of gametes will be produced, such as F and f, and will form Ff and ff offspring when crossed with the freckleless parent (ff).
Hence, a freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.

Describe Charles Darwin's theory of natural selection
Answer:
it sghwbdhfbwahdfk
Explanation:
Answer:
Explanation:
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.
How will answering this question help scientists develop their understanding of how CRISPR-Cas9 can help solve the problem of antibiotic resistance?
bacteria can evolve over time, take penicillin as an example, when the scientists figure that out, they can't prevent bacteria from evolving
In Marker Analysis, how are STRs related to alleles? Be sure to define each term (STR and allele) and explain how the two result in different band patterns when run in gel electrophroresis.
Answer:
The number of STR repeats is unique and therefore it is considered as an allele of that locus
Explanation:
Short Tandem Repeats (STRs), also known as microsatellites or simple sequence repeats (SSRs), are short DNA sequences with a size of 1-6 nucleotide bases which may be many times repeated in tandem. STRs localize in specific regions of the genome (loci) and therefore they are molecular markers. Gel electrophoresis a technique used to separate DNA fragments based on their size. In consequence, the pattern of STR repeats or 'alleles' obtained by electrophoresis can be used to identify individuals. In a gel electrophoresis, STR markers produce different bands that run more slowly or faster on the gel in different lanes according to their size (e.g., more slowly >> higher size of the STR sequence), and thereby STR alleles are unique and serve to identify individuals.
A substace put in a space or cantainer to fill it, usually applied in wood to fill up cracks and grooves
Answer:
Glue and sawdust.
Explanation:
Glue and sawdust are the substances that applied in wood to fill up cracks and grooves. You can use the glue and sawdust method to fill the gaps present in the wood. This method is a quick and easy solution that successfully fill up the gaps and grooves on the wood. The method of using this method is, first fill the gap with a small amount of wood glue, then rub sawdust into the gap which attached the saw dust with itself and the gaps are filled.

How are food webs used to help explain ecosystem interactions?
Food webs used to help explain ecosystem interaction as the food web shows the flow of energy from one organism to another.
What is Food web?Food webs have been defined as important conceptual tools for delineating feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.
It is defined as a graphical representation of the natural interconnection of food chains and what-eats-what in an ecological community. Food web is also called consumer-resource system.
Example of Food web is Falcon eats snake, which has eaten frog, which has eaten grasshopper, which has eaten grass. A food web shows the many different pathways where plants and animals are connected
Thus, Food webs used to help explain ecosystem interaction as the food web shows the flow of energy from one organism to another.

Sand for beaches comes from rocks in the area that are weathered down, and
their sediment is deposited in the area beaches. The beaches are then eroded,
and the sediment is moved away from the beaches. If rocks stopped weathering,
how would the beach change?
Answer:
Beaches would shrink until they were no longer there because the sediment is pulled away from the shores by the tide and there would be no new rock sediment to replace the old rock sediment.

An area surrounded by tall mountains contains a very large, isolated population of green and white peacocks. During the mating season, the male peacocks demonstrate flashy feather displays to attract females, who usually choose green peacocks over white ones. A biology student tabulates the following information.
Genotype
Plumage Color % of Population Allele Controlled Phenotype
FF or Ff
Dark green
84%
F (dominant)
Dark green plumage
ff
White
16%
f (recessive)
White plumage
Using this information, the student plans to use the Hardy-Weinberg equation to predict the allele frequencies in future peacock generations. Why would her research advisor have a problem with this? (2 points)
Group of answer choices
The student needs the percent of the population with the Ff genotype in order to find the F frequency.
Her research advisor would first want her to find the males' mating success rate for the calculations.
The peacocks are sexually selective when choosing mates, so future allele frequencies may drift.
Since the peacock population is isolated, its alleles would shift away from Hardy-Weinberg equilibrium.

Answer:
biodiversity mean Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth.
Explanation:
Answer: Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.
Explanation: Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.
Genetic diversity is all the different genes contained in all individualplants, animals, fungi, and microorganisms. It occurs within a species as
well as between species.
Species diversity is all the differences within and between populationsof species, as well as between different species.
Ecosystem diversity is all the different habitats, biological communities,and ecological processes, as well as variation within individual ecosystems.
