Consider a diploid organism. What is the genotypic ratio expected to be observed in the offspring produced by two heterozygous parents
Answer:
See the answer below
Explanation:
A diploid organism is one that has 2 copies of each of its genes. When the two genes are the same, they are said to be homzygous, and when they are different, they are said to be heterozygous.
In this case, let us assume that the trait in question is represented by A for the dominant version and a for the recessive version. Since the parents are heterozygous, it means their genotypes would be Aa.
Aa x Aa
AA Aa Aa aa
Hence, the genotype ratio would be 1AA:2Aa:1aa. In other words, the genotypic ratio of homzygous to heterozygous offspring would be 1:1 because AA and aa are both homzygous while Aa is heterozygous.
The geno-typic ratio expected to be observed is 1:1
The following information should be considerd:
A diploid organism is that where it has 2 copies of each of its genes.When the two genes are similar, they are said to be homo-zygous else hetero-zygous.Since the parents are heterozygous, it means their genotypes would be Aa.
Aa x Aa
AA Aa Aa aa
So here the ratio should be 1:1

Factors that affect drug absorption include: (Choose the best answer.) Group of answer choices Protein-binding properties of the drug molecule Ability to chew and swallow Liver enzyme activity Lipid solubility of the drug
Answer:
The Factor that most affects drug absorption s the Lipid solubility of the drug
Explanation:
For a drug to accomplish its pharmacological function, it needs to suffer absorption mechanisms.
Most drugs, those that do not act locally, need to be correctly concentrated in their action sites or target sites. The first step is absorption.
This involves the obligated pass through the semipermeable plasmatic membrane to finally get in the blood. In blood, the drug moves, distributes, metabolizes, and the unaltered molecules are excreted.
There are different mechanisms in which drugs can cross the membrane that depends on the drug type. Depending on the effects of these mechanisms, there will be a more or less concentrated drug at the target sites.

If the amount of pollution is the same in the ocean where the fish are being caught, why
might some fish have more of this toxin than others?
Answer:
Because they might be taking in a higher concentration of the toxin through food or their environment or others could just be older meaning theyve ingested more of the toxin overtime
Explanation:
The level of toxin in fishes that lives in the area of the same pollution may differ due to the ability to consume toxins.
What do you mean by Toxins?Toxins may be defined as a poisonous substance that is a specific product of the metabolic activities of a living organism and is usually very unstable, notably toxic when introduced into the tissues, and typically capable of inducing antibody formation.
While living in the area or habitat of the same pollution, still some fishes have more of this toxin than others. This is because these fishes have the ability to consume toxins from food resources that are present in the same habitat. While some fishes consume high toxins, but in results, they do not have the ability to resist in the high level of toxins, so they get eliminated or died.
Therefore, the level of toxin in fishes that lives in the area of the same pollution may differ due to the ability to consume toxins.

Amino acids have similar structures. What part of an amino acid's molecular formula distinguishes the macromolecule from other amino acids?
O the R-group
o the amino group
o the carboxyl group
O the nitrogenous base W
Answer:
The R-group
Explanation:
Amino acids are organic compounds that combine to form proteins. There are 20 of them, out of which 9 are essential. All of them have a similar structure: they consist of an alpha (α) carbon atom bonded to an amino group (NH2), a carboxyl group (COOH), a hydrogen atom, and an R group. The R group is the organic component, a side chain, that is unique to each amino acid.
This is why the first option is the correct one.
Answer:
the R-group

Some similarities are....
They are both biomolecules, both are nucleic acids, they are both involved in the making of proteins, both contain genetic information.
Some differences are...
DNA = Double-stranded
RNA = Singer-stranded
DNA = The sugar moiety is deoxy ribose
RNA = Ribose is the main sugar
DNA = Thymine is always there, but uracil is never found
RNA = Pyrimidine components differ. Thymine is never found
DNA = It follows Chargaffs rule (since it's double stranded)
RNA = Doesn't follow Chargaffs rule (since it's single stranded)

What structure do plant cells have during cytokinesis that animal cells do not have?
Answer:
During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast.

What do you call the process of water seeping into the ground?
Answer:
Process of seeping (flow or leak slowly through a porous material or small holes) of water into the ground is called infiltration. Infiltration is the process by which water on the ground surface enters the soil.
Water not used by plants moves deeper into the ground. The top of the water in the soil, sand, or rocks is called the water table and the water that fills the empty spaces and cracks is called groundwater. Water seeping down from the land surface adds to the groundwater and is called recharge water.
Hence The process of water seepage into the ground is called Infiltration.

False
Answer:
True
Explanation:
This is because as mantle convection slowly creep molecules that are warmer into the motion or movement in mantle cells, the cooler part of the rock move out of the mantle in the earth, convection currents continue to flow that carries heat into the mantle core. The mantle remain solid, the convection current that carry heat to the core, cause deformation of geologic structures on the mantle.
Fruit production in anthophytes develops from: a. a female reproductive structure b. a male reproductive structure c. both male and female reproductive structures d. photosynthetic signals
Answer:
a. a female reproductive structure
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.
Division Antophyta are classified into two (2) main categories and these includes;
I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.
II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.
Basically, fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.
