Unattached earlobes is a dominant trait, E. A parent who is homozygous for unattached earlobes is crossed with a parent who is
homozygous for attached earlobes. Which describes the genotypes of their offspring?
100 percent Ee
100 percent unattached earlobes
100 percent ee
100 percent attached earlobes
Answer:
100 percent Ee
Explanation:
This is a cross involving a single gene coding for attachment or not of earlobes. The allele for unattached earlobes (E) is dominant over the allele for attached earlobe (e). This means that allele E will always mask the phenotypic expression of e in a heterozygous state.
A parent that has same alleles for unattached earlobes i.e. EE is crossed with a parent that has same alleles for attached earlobes i.e. ee. In this cross, all of the offsprings will have a heterozygous genotype, Ee because gametes E and e will be produced respectively by each parent.
Hence, since all of the offsprings will have an Ee genotype, it means 100% of their offsprings will have Ee (HETEROZYGOUS).

What kind of genetic factors affect algae growth?
ANSWER :
Algae prefer stable conditions. Low water levels create slower, more uniform conditions that encourage algae growth. Warmer water leads to increased algae growth. The temperature of the water may even favor the growth of certain types of algae over others. Nutrients, like nitrogen and phosphorus, fuel algae growth; however, excess nutrients from human activities can exacerbate algae blooms.What is the lava like that produces an eruption like this one?

Match each environmental change with its description.
Chemicals react with water and oxygen that enter water systems.
arrowBoth
Nutrients in excessive amounts enter water systems, causing algal bloom.
arrowBoth
A high concentration of toxic chemicals is present in the bodies of animals at the highest trophic levels.
arrowBoth
Answer:
The question is incomplete, the missing part i.e. the environmental change is:
(A) biomagnification
(B) acid rain
(C) eutrophication
The answers are:
1. Acid rain- Chemicals react with water and oxygen that enter water systems.
2. Eutrophication- Nutrients in excessive amounts enter water systems, causing algal bloom.
3. Biomagnification- A high concentration of toxic chemicals is present in the bodies of animals at the highest trophic levels
Explanation:
1. Acid rain is an environmental disorder in which rainfall becomes acidic due to pollution. The pollution is as a result of the release of gaseous chemicals e.g sulfur, nitrogen oxide, which are produced by industries, into the atmosphere. These chemicals then react with water in the atmosphere to form acidic solutions, which then falls back as rain. Hence, chemicals reacting with water and oxygen that enter water systems describes ACID RAIN.
2. Eutrophication is the pollution of water bodies with substances containing chemicals like nitrogen, phosphorus etc. The chemicals, which are in excess, serve as nutrients to algae, which uses them to grow excessively forming a bloom called ALGA BLOOM. Hence, nutrients in excessive amounts entering water systems, causing algal bloom describes EUTROPHICATION.
3. Biomagnification refers to the build up or accumulation of toxic chemical substances in the body systems of living organisms higher up in the food chain. Pollutants like pesticides, herbicides flow into water bodies and are absorbed by certain aquatic organisms. When these organisms are fed on by consumers, the harmful substances accumulates in their tissues until it reaches a maximum concentration. Hence, a high concentration of toxic chemicals present in the bodies of animals at the highest trophic levels describes BIOMAGNIFICATION.
Answer:
1. Acid rain- Chemicals react with water and oxygen that enter water systems.
2. Eutrophication- Nutrients in excessive amounts enter water systems, causing algal bloom.
3. Biomagnification- A high concentration of toxic chemicals is present in the bodies of anima

which is not an example of inorganic fertilizer? A.nitrogen fertilizer B.phosphorus fertilizer C. Livestock waste
Answer:
Livestock waste
Explanation:
Fertilizers supplement the soil with macronutrients needed in large amounts: nitrogen, phosphorous and potassium. However, organic and inorganic fertilizers do so via different materials. Organic fertilizers contain only plant- or animal-based materials that are either a byproduct or end product of naturally occurring processes, such as manures, leaves, and compost.
Inorganic fertilizer, also referred to as synthetic fertilizer, is manufactured artificially and contains minerals or synthetic chemicals. For example, synthetic nitrogen fertilizers are typically made from petroleum or natural gas. Phosphorus, potassium and other trace elements in inorganic fertilizers are often mined from the earth. Balanced inorganic fertilizers, high in all three macronutrients, commonly include products like ammonium nitrate, ammonium sulfate, potassium chloride (potash), triple superphosphate, and magnesium sulfate (Epsom salts).

mitosis, meiosis, and the formation of the final protein
transcription, mitosis, and DNA replication
Answer:
A.
Explanation:
The cells control gene expression at transcription, translation, and the formation of the final protein.
What do you mean by gene expression?Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, protein or non-coding RNA, and ultimately affect a phenotype, as the final effect.
Gene expression is the process by which the information encoded in a gene is turned into a function. This mostly occurs via the transcription of RNA molecules that code for proteins or non-coding RNA molecules that serve other functions.
Gene expression is a tightly regulated process that allows a cell to respond to its changing environment. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
