Answers

Answer:

geothermal energy

Explanation:

volcanic geothermal energy, the heat comes from "supercritical water." The researchers explained that energy from so-called supercritical water is much higher than conventional geothermal steam. When molten rock and water meet, the extreme heat and pressure bring water to a "supercritical" state, where it is neither liquid nor gas.

If something is 12 grams and has a volume of 1.6 cubic centimeters, how many grams per cubic centimeter.

Answers

Answer: 7.5  grams per cubic centimeter.

Explanation:

We area given that , Mass of something is 12 grams

Volume of that thing is 1.6 cubic centimeters

To find gram per cubic centimeters, we will divide Mass by Volume ( which computes Density)

Number of gram per cubic centimeters = [tex]\dfrac{12}{1.6}[/tex]

Number of gram per cubic centimeters = 7.5

Therefore, 7.5  grams per cubic centimeter. (density of the thing)

The diagram below represents the time a cell spends in the two main phases
of the cell cycle. In which phase does a cell spend more time?
A. Prophase
B. Mitosis
C. Meiosis
D. Interphase

Answers

Answer:b

Explanation:

The cell spends more time in the meiosis phase. Therefore, option "C" is correct.

What is meiosis?

Meiosis is a type of cell division in sexually reproducing organisms, therefore, producing gametes. In this process, the number of chromosomes is reduced in the gametes. These cells are known as haploid cells. The examples are sperm and ovum.

There are two phases of meiosis: meiosis I and meiosis II. Meiosis I has four stages whereas meiosis II has three stages. In meiosis I, a cell divides into two genetically distinct haploid cells. In meiosis II, the two divided haploid cells divide further in two cells. Total four cells are produced in the process of meiosis.

Meiosis is an important cell division process in sexually reproducing organisms. It is used in the production of gametes in both males and females organisms.

Therefore, meiosis take more time than mitosis due to double stages.

explain the absorption of mineral by root hair cell if all mithochondria remove from the cell .​

Answers

Answer:

The root hair cells have carrier proteins in their cell membranes. These pick up the mineral ions and move them across the membrane into the cell against the concentration gradient . Because active transport moves ions against the concentration gradient into the root hair cells, energy is needed.Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.

In an experiment, two populations of one species of fruit flies were raised for several generations on different nutrients (starch and maltose). Then the members of the two populations were reintroduced and the mating frequencies of flies from the two different populations were recorded. Fruit flies fed on starch were more likely to mate with other starch fruit flies. The same was the case for maltose fruit flies. When they did mate, their offspring were infertile. The fruit flies are physically indistinguishable and genetically similar.

Match the characteristic with the correct species concept definition.

Physiologically similar ---- morphological concept

Genetically similar ---- phylogenetic concept

Feed on starch or maltose ---- ecological concept.

Explanation:

Hybrids are fertile is a biological characteristics of an organism, physiologically similar is a morphological characteristic of a specie, genetically similar is a phylogenetic characteristic of a specie and feed on starch or maltose is a ecological characteristic of an organism. The ability of two individuals to successfully produce fertile offspring is biological species concept whether individuals look similar is a morphological species concept closely related individuals are evolutionarily or phylogenetic species concept.

What happens to interspecific and
intraspecific competition as habitats
decline?
A. competition increases
B. it depends on the habitat
C. competition remains the same

Answers

Answer is A because the habitat’s resources are depleting

Members of the same species compete with one another within their own species, hence option A is correct.

What is the interspecific and intraspecific competition?

It demonstrates the adaptability of the species. Members of various species compete with one another across interspecific boundaries. It might result in the extinction of one species or the specialization of both.

In a population, individuals develop, procreate, and pass away. The needs of individuals within a population for survival, growth, and reproduction are quite similar. The result is frequently intraspecific competition.

The fitness of both populations is impacted by competition. The investment of resources (energy, time, and matter) in competition or avoidance of it diminishes the availability of these resources and has a negative impact on the population's ability to reproduce.

Therefore, option A is correct.

What is the dominant phenotype of the offspring in the cross shown?


A.Ff
B.FF
C.blue
d.white

Answers

Answer:

C. blue  

Explanation:

In genetics, homo-zygous individuals are those individuals that have the same allele form (i.e., the same allele) for a given gene/locus, whereas heterozygous individuals have different alleles for that gene/locus. Complete dominance is a form of dominance that occurs when the allele that is dominant for a given gene/locus completely masks the effects of the recessive allele in a heterozygous individual. In this case, individuals that are heterozygous (genotype Ff) exhibit a dominant flower-blue phenotype because the dominant 'F' allele completely masks the effect of the recessive 'f'  allele; therefore producing a phenotypic ratio of 3:1 in the offspring of a mating between two heterozygous individuals for this single trait.

What is a dominant allele?
A. In a heterozygous individual, the allele that determines the phenotype
B. An allele that will only have an affect on phenotype in a haploid organism; otherwise its presence will be masked
C. An allele that is very prevalent in a population
D. An allele that totally beats up on a recessive allele
E. An allele that has no noticeable affect on an organism's phenotype

Answers

Answer:

A. In a heterozygous individual, the allele that determines the phenotype

Explanation:

The dominant allele completely hides the expression of the recessive allele. This occurs in cases of Autosomal dominant inheritance. Even when both dominant and recessive alleles are present in the genotype, this is the heterozygous state, only the dominant trait will be expressed. Only one dominant allele is enough to express the dominant phenotype.

Nature constantly adjusts the atmospheric carbon level. An increase in the level causes the atmosphere to hold more heat, which causes more water to evaporate from the oceans, which causes increased rain. Rain washes some carbon from the air into the oceans, where it eventually becomes part of the seabed. A decrease in atmospheric carbon causes the atmosphere to hold less heat, which causes decreased evaporation from the oceans, which causes less rain, and thus less carbon is washed into the oceans. Yet some environmentalists worry that burning fossil fuels may raise atmospheric carbon to a dangerous level. It is true that a sustained increase would threaten human life. But the environmentalists should relax—nature will continually adjust the carbon level.

Which one of the following, if true, would most weaken the argument in the passage?

(A) Plant life cannot survive without atmospheric carbon.
(B) It is not clear that breathing excess carbon in the atmosphere will have a negative effect on human life.
(C) Carbon is part of the chemical "blanket" that keeps the Earth warm enough to sustain human life.
(D) Breathing by animals releases almost 30 times as much carbon as does the burning of fossil fuels.
(E) The natural adjustment process, which occurs over millions of years, allows wide fluctuations in the carbon level in the short term.

Answers

Answer: E) The natural adjustment process, which occurs over millions of years, allows wide fluctuations in the carbon level in the short term.

Explanation:

If the natural adjustment process takes millions of years then it nature will not be able to adjust the levels of carbon in the atmosphere fast enough. This means that in the short term, carbon levels will fluctuate widely if more fossil fuels are burnt.

It is therefore necessary that humans reduce how much fossil fuels that burn to ensure that in the short term, situations on earth are manageable while the adjustment process goes on for millions of years.
