what is the independent and dependent variable in this experiment?

Group 1:Hand Sanitizer Bacteria growth:28
Group 2:Soap A. Bacteria Growth:12
Group C: Soap B. Bacteria Growth:13
Group 4: Warm Water. Bacteria Growth:24​

Answers

Answer 1

Answer:

Independents are all the different liquids used ie: soaps, water, hand sanitizer.

Dependent is the bacteria growth.

Explanation:

This is because you are constantly change the liquids so that is independent. The bacteria growth is dependent since the growth depends on the different liquids.

PLEASE I NEED HELP ASAP!! WILL GIVE BRAINLIEST AND 100 POINTS!!! When you cross two heterozygous organisms, what is the probability that the offspring will show the dominant phenotype? (HINT: You may want to draw a Punnett Square on a separate piece of paper to help.)
A. 100
B. 75
C. 50
D. 25
E. 0

Answers

Answer

75% chance

Explanation:

The dominant and recessive are the terms used to explain the phenotypic traits and genetic makeup of an organism. The cross between a heterozygous species will result in a 75% chance of the species expressing a dominant phenotype.

The correct answer is:

Option B. 75%

The heterozygous condition refers to the one dominant and one recessive allele, whereas purebred is the condition in which both alleles are either recessive or dominant.

The dominant alleles are always expressed in purebred and heterozygous conditions.

The recessive alleles are expressed in purebred conditions only.

In the given attachment, consider the cross between round shaped-seeds in heterozygous conditions.

Thus, the chance of progeny will have round-shaped seeds is 75%.

which is true regarding the process of meiosis I?
A) chromosome Number is reduced from diploid to haploid
B) sister chromatids in a cell undergoing are always identical
C) Most homologue pairs do not have any crossovers during prophase I
D) sister chromatids separate to opposite ends of the cell

Answers

Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)

Explanation:

In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.

Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.

A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:

--> the chromosomes replicate once and

--> the nucleus and cell duplicate ( divide equally) twice.

As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.

What are two genotypes that could produce a dominant phenotype?

Answers

Answer:

A homo-zygous dominant genotype and a heterozygous genotype

Explanation:

A homo-zygous dominant genotype refers to a genotype that contains two copies of the dominant gene variant, i.e., two dominant alleles at its locus, thereby individuals carrying this genotype will show a dominant phenotype. Moreover, a heterozygous genotype is a genotype that contains both dominant and recessive alleles at its locus. In a heterozygous genotype, the dominant allele is always expressed and masks the recessive allele, thereby showing a dominant phenotype.

Is it varration , overpopulation or adaption On average, sea turtles lay about 110 eggs in a clutch. However, only a fraction of the baby turtles make it to the ocean. Then, an even smaller number have offspring of their own.

Answers

Answer: this is adaptation, but not in the way suggested in the question.

Explanation:

The question is suggesting that the 1% or so of turtle hatchlings that make it to maturity are the result of a variation that gives a selective advantage. This is not so. The only thing being selected for is sheer luck. The underlying adaptation is that all eggs hatch within a short period, so that predators are overwhelmed by numbers and some offspring by chance make it to the water, still dangerous, but less so than the sand. After the hatchlings reach the sea chance will still be a factor, but it is at this stage that natural selection may operate on advantageous variations.

There are two reproductive strategies, common to plants as well as animals. Turtles represent one of those strategies, which is to invest resources to produce large numbers of immediately self-sufficient offspring so that at least some will survive. The other strategy is to produce one or few offspring and invest resources in protecting and feeding it or them until self-sufficient and capable of surviving to maturity.

These are adaptations which are selected for because they confer advantage for the species concerned. One or the other may be the better solution depending on the species. Mammals, for example, invest in the latter strategy.

Movement of the particles across the membrane stops when the concentration gradient no longer exists, the particles will continue to diffuse due to random motion

Answers

Answer:

Once the concentration gradient no longer exists, particles will continue to diffuse due to random motion.

Explanation:

When there is a permeable membrane between two solutions with different concentrations, the concentration gradient will go from the compartment with more particles to the one with fewer particles to valance the concentrations on both sides of the membrane. Once the concentrations are equal, particles will still randomly move from one side to the other, but the number of particles that move to one side is almost the same as the number of particles that move to the other, so there is still valance and the same concentration in both sides.
