A(n) ecosystem is all the living and nonliving things in a particular area that interact with one another.
What is an ecosystem?A(n) ecosystem is all the living and nonliving things in a particular area that interact with one another. An ecosystem includes the living organisms (plants, animals, and microbes) and the nonliving components (water, air, and soil) that make up the environment in a specific area.
These living and nonliving components of an ecosystem interact with one another, forming complex relationships and feedback loops that help to sustain the ecosystem over time. Ecosystems can vary in size from small ponds to vast oceans, and they can be found in a wide range of environments, from deserts to rainforests.

Polysaccharides are 1000s of monosaccharides joined together.These carbohydrates store energy and help build structural compounds. For example, plants use cellulose to build up their cell walls so they can stay rigid and grow towards the sunlight. Plants can store glucose energy in the form of starch in roots, fruits, and seeds. On the other hand, animals store glucose energy in the form of glycogen. When we don't have enough food to eat to replenish glucose in our cells, glycogen will release glucose energy as backup.
True or False??
Answer:
True
Explanation:
As rightly stated in this question, Glycogen is a carbohydrate which animalsa store glucose energy as. When we eat food, all parts is not converted to glucose, some is converted to glycogen, which is then stored in the liver and muscle tissues.
This stored glycogen, which is a polymer of glucose is broken down to glucose for use during a low supply of glucose to the cells. Hence, it is TRUE that when we don't have enough food to eat to replenish glucose in our cells, glycogen will release glucose energy as backup.

What are the products of cellular respiration?
Answer ASAP test due
Most of the steps of cellular respiration take place in the mitochondria. Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
The products of cellular respiration are water, carbon dioxide and energy (ATP). Details about cellular respiration can be found below.
What is cellular respiration?Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells.
Cellular respiration involves the reaction of glucose and oxygen molecules as reactants to synthesize carbon dioxide gas, water and ATP molecules.
Therefore, the products of cellular respiration are water, carbon dioxide and energy (ATP).

In pea plants, round seed shape (R) is dominant over wrinkled (r). Write the genotype for a plant that is heterozygous.
Answer:
Rr, heterozygous traits have one recessive and one dominant, therefor meaning its going to be Rr
Answer:
R.r
Explanation:
Hetero = different
Hom0 = same
An individual hom0zygous for a particular trait has two of the same allele at the gene. In this case, it would either be R.R or r.r.
An individual heterozygous for a particular trait has two different alleles, in this case it is R.r.
Restriction enzymes: A) act at the membrane to restrict the passage of certain molecules into the cell. B) are highly specialized ribonucleases that degrade mRNA soon after its synthesis. C) are sequence-specific DNA endonucleases. D) are very specific proteases that cleave peptides at only certain sequences. E) catalyze the addition of a certain amino acid to a specific tRNA. c The biological role of restriction enzymes is to: A) aid recombinant DNA research. B) degrade foreign DNA that enters a bacterium. C) make bacteria resistant to antibiotics. D) restrict the damage to DNA by ultraviolet light. E) restrict the size of DNA in certain bacteria.
Answer:
C) are sequence-specific DNA endonucleases
Explanation:
Restriction enzymes represent a type enzyme capable of recognizing short nucleotide sequences to cut at specific restriction sites in the DNA, these sites are known as target DNA sequences. Some of the most commonly used restriction enzymes are EcoRI, BamHI and HindIII, isolated from Escherichia coli, Bacillus amyloliquefaciens and Haemophilus influenza, respectively. Restriction enzymes are endonucleases because these enzymes only cleave the phosphodiester bond within the DNA chain, conversely to exonucleases, which cleave nucleotides from the end of the polynucleotide DNA strand.
What common thing occurs in each mutation?
Which of the following factors is most likely to decrease the stability of an ecosystem?
A
The removal of a species
B
An increase in plant biodiversity
C
The removal of an individual animal
D
An increase in animal biodiversity
Answer:
A
Explanation:
The removal of a species can reduce the food source of another species, which can cause that species to slowly die out, where other animals that consume the dying species start dying out... ect.
So it decreases the biodiversity which can mess with populations.
If the species is a herbivore, it could cause the plants that are eaten by that herbivore to get out of control in population, which can fight for sunlight and resources with other species causing ecosystem collapse.
In an ecosystem, the removal of a species can decrease the stability. Thus, option A is correct.
What are the biotic factors of an ecosystem ?Biotic factors are the basic unit of ecosystem where the living beings interact with each other and their environment.
There are two components of an ecosystem such as biotic and abiotic components, include distribution of energy in our environment.
Biotic components can be classified into autotrophs, heterotrophs and decomposers based on mode of nutrition.
Autotrophs are producer such as plants as they produce food through the process of photosynthesis.
Heterotrophs are the consumer depend on producer for their nutrient, which is further classified into three categories.
Primary consumers are herbivores rely on producers for food while secondary consumers depend on primary consumers. They can be carnivores or omnivores.
Tertiary consumers depend on secondary consumers for food. some quaternary consumers are also seen in some food chains.
Decomposers include saprophytes such as fungi and bacteria which lie on decaying organic matter and essential for the ecosystem
Hence, option A is correct.

In a population of frogs, there is a dominant allele H that improves the survival of eggs in moderately dry conditions compared to the wild-type and recessive h allele. Imagine that climate change causes the environment where these frogs live to become more dry. Individuals with the drought-resistant eggs on average have 21 viable offspring per frog per generation, whereas those without that phenotype on average have only 12. If we start off with genotype frequencies of .02 HH, .03 Hh, and .95 hh, what is the average excess fitness of the H allele?
Answer:
8.55
Explanation:
I n the year1908, these two men Godfrey Hardy and Wilhelm Weinberg gave a specification of the relationship between the frequency of genotype and frequencies of allele that should occur when such a population is in equilibrium
p²+2pq+q² = 1
we have,
p² = 0.02
p = √0.02
such that frequency of H is = 0.1414
2pq = 0.03
q² = 0.95
q= √0.95
such that frequency of h =0.9746
(21-12) * 0.95 =
8.55 frogs per generation
H and h will coexist.

the genotype or the phenotype? Explain
Answer:
Phenotype
Explanation:
It's phenotype because a genotype is not a physical trait; a genotype means genes. It's phenotype because it a physical trait you can see. Lets say twins look the same on the outside but on the inside they have completely DNA. This is like how some butterflies look the same with orange wings but one might have a mutation in its genes.
