using the particulate model of matter explain why gases can be compressed easily?
Explanation:
Use the particle model of matter to explain why solids have a fixed shape, but gases fill the shape of the container they are in. ... The particles in a gas have very large spaces between them, so the particles can be 'squashed' closer together, meaning the gas can easily be compressed to take up a smaller volume.
The gamete of a red fox has 19 chromosomes in it. How many chromosomes are in the red foxes DIPLOID skin cells?
Answer:
38 chromosomes are in the red foxes DIPLOID skin cells
Explanation:
There are two principal types of cells in the organism:
Diploid cells (2n) Somatic diploid cells (2n) reproduce by the process of mitosis and produce two diploid cells.Germ diploid reproductive cells (2n) also reproduce by mitosis and produce two diploid cells. But can also reproduce by the process of meiosis, suffering a reduction in the number of chromosomes and producing four haploid cells (n). Haploid cells (n)Gametes are the product of germ cell division by meiosis, and they have only one set of chromosomes, n (19 in this example). Their destiny is to merge in the process of fecundation, during which a new diploid cell called the zygote emerges through fertilization. The zygote is a complete diploid cell that suffers successive mitosis and forms a new organism (a new fox in this case).
- So, through meiosis, the diploid germ cell (2n) produces four haploid cells (n) that are the gametes.
- Through fecundation or fertilization, two gametes (n) merge and produce a diploid cell (2n) that is the zygote.
If the red fox gamete has 19 chromosomes (haploid number n, the single set of chromosomes), it must merge with another gamete (coming from the other parent) with 19 chromosomes to form the zygote. The zygote is a diploid cell. The zygote will suffer many mitosis divisions to become a new fox.
To know the number of chromosomes in a skin cell, we need to duplicate the number of chromosomes in the gamete (19).
N = 19 = Haploid number2N = 2 x 19 = 38 = Diploid numberWhich structure helps fish remove oxygen from the surrounding water?
Answer:
Gills
Explanation:
In order to remove oxygen from the water, they rely on special organs called "gills." Gills are feathery organs full of blood vessels. A fish breathes by taking water into its mouth and forcing it out through the gill passages.

If the code on the template DNA strand is TACGCA the RNA built from that template during transcription would have the sequence type your answer..
Answer:
AUGCGU
Explanation:
According to the base-pairing rule, Thymine (T) always pairs with Adenine (A), and Cytosine (C) always pairs with Guanine (G). In addition, RNA has Uracil (U) in the place of Thymine. Following these two rules, TACGCA is transcribed as follows:
T A C G C A
A U G C G U
Hence, the transcription product of TACGCA is AUGCGU.
What is carbon emissions responsible for?
Answer:
Carbon dioxide (CO2) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity.
Explanation:
What can Carbon do?
Carbon emissions affect the planet significantly, as they are the greenhouse gas with the highest levels of emissions in the atmosphere. This, of course, causes global warming and ultimately, climate change. Carbon dioxide is released into the atmosphere when fossil fuels — coal, natural gas, and oil — are burned.

How does seed formation take place in plant? explain.
Answer:
Seeds are the result of plant reproduction. ... When pollen lands on the flower's stigma, it germinates and forms a pollen tube, which then quickly grows towards the plant's ovary. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation.

What are two genotypes that could produce a dominant phenotype?
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.
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
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%.

Bees can pollinate all types of flowers.
Answer:
Yes,it's clear that bees play a vital role in food production. They are excellent pollinators! Most food crops—including fruits, vegetables, nuts, and seeds—must go through pollination. That's the process of moving tiny pollen cells between plants to help them make seeds.

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.
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.
