A.
The total amount of matter on Earth constantly decreases.
B.
The total amount of matter on Earth is always changing.
C.
The total amount of matter on Earth constantly increases.
D.
The total amount of matter on Earth remains constant.

Answers

Answer:

The answer is D. The total amount of matter on Earth remains constant

Explanation:

I just did this and its the correct outcome :/ Hope it helps

Final answer:

The total amount of matter on Earth remains constant as it cycles through different environmental reservoirs, adhering to the law of conservation of matter.

Explanation:

Matter on Earth cycles through different reservoirs, such as the atmosphere, biosphere, hydrosphere, and geosphere. This cycling involves processes like photosynthesis, respiration, and decomposition. Despite the complex transformations and exchanges, the total amount of matter remains constant due to the law of conservation of matter. This principle states that matter is neither created nor destroyed within a closed system. Consequently, as matter cycles through the Earth's reservoirs, the effect on the total amount of matter is that it remains constant.

The correct answer to the question is:

D. The total amount of matter on Earth remains constant.

Explanation:

can mutations occur in both DNA and RNA nucleic acids ?

Answers

Answer:

Yes

Explanation:

All mutations will be passed onto new cells through DNA replication, and all RNA made from that DNA will also have the mutation. If the mutation occurs in sperm or egg cells, those mutations will also be passed on to the organism's offspring.

Yes, both DNA and RNA nucleic acids may experience mutations. Mutations are modifications to the nucleotide sequence in a DNA or RNA molecule. Errors in the replication process, environmental variables, or other outside forces may be at blame for these modifications.

Both the coding sequence and the non-coding portions of DNA are susceptible to mutation. The structure and function of the protein can be impacted by variations in the amino acid sequence caused by mutations in the protein's coding sequence.

Changes in the gene's expression may be caused by mutations in the non-coding areas. Both the coding sequence and the non-coding portions of RNA are susceptible to mutation. Changes in the amino acid sequence of the protein can result from mutations in the coding sequence.

Diagram of the sun.

The sun is the old star in the solar system that is able of generating light and heat that reaches all corners of the universe. The sun is arranged into various layers such as those of the sub-layers are the photosphere, chromosphere, and other layers.

Thus the answer is 1. chromosphere, 2. photosphere, 3. inner core, 4. corona, 6. Prominence.

The layers of the sun are arranged and they refer to the way the sun is made and composed. As the sun is a mix of hydrogen and helium gases that are made from the fusion and fission of atoms. The layer helps the sun to be a star.

Learn more about the diagram of the sun.

brainly.com/question/22756425.

The Sun comprises a core with nuclear fusion, a radiative zone for energy transport, a convection zone with plasma currents, a visible photosphere, a reddish chromosphere, a transition region, and a hot outer corona extending into space.

Core: At the Sun's core, temperatures and pressures are extremely high, allowing nuclear fusion to occur. Hydrogen atoms fuse to form helium, releasing an enormous amount of energy in the process.

Radiative Zone: Energy produced in the core is transported outward through the radiative zone. Photons generated in the core travel through this zone, bouncing between particles, gradually making their way to the surface.

Photosphere: The Sun's visible surface is the photosphere. This is where most of the Sun's energy is emitted as light and heat. Sunspots, which are cooler and darker areas, can be observed on the photosphere.

Chromosphere: Above the photosphere lies the chromosphere, a layer of the Sun's atmosphere. It is characterized by a reddish glow and is visible during solar eclipses.

Corona: The outermost layer of the Sun's atmosphere is the corona. It is composed of extremely hot, ionized gas, and it extends into space. The corona is visible during a solar eclipse.

Group of answer choices

deuterostome; triploblast

triploblast; pseudocoelomate

triploblast; coelomate

triploblast; acoelomate

Answers

A planarian is an example of a triploblast and is also an acoelomate as it does not have a coelom but still has a gut cavity. correct answer is triploblast; acoelomate.

A planarian is an example of a triploblast, which is an organism that has three primary germ layers: ectoderm, mesoderm, and endoderm. In the context of body cavity development, planarians are classified as acoelomates because they do not have a coelom. Their mesoderm is completely filled with tissue, but they still have a gut cavity. Animals such as planarians that belong to the phylum Platyhelminthes exhibit this trait, distinguishing them from eucoelomates, which have a true coelom, and from pseudocoelomates, which have a body cavity that is not completely lined by mesoderm. correct answer is triploblast; acoelomate.

Match the signs of development with the appropriate trimester.

Fingerprints have developed.
The fetus can hear and see.
The heart beats for the first time.
Nerve cells have developed.
The sex can be determined.
Fat begins to develop.
The fetus starts to move

Answers

Final answer:

Signs of fetal development like fingerprints and the ability to hear are associated with the second trimester, while the first heartbeat occurs in the first trimester. Determination of sex is possible between 9-12 weeks, and significant fat development takes place in the third trimester. Early movement starts as soon as the sixth week.

Explanation:

To match the signs of fetal development with the appropriate trimester:

Fingerprints have developed: This occurs in the second trimester, as fingers and toes are fully developed around the 16-week mark.The fetus can hear and see: Significant hearing development happens between weeks 16 and 26, while vision development continues throughout pregnancy, with light detection capability emerging later.The heart beats for the first time: This critical stage happens in the first trimester, at about six weeks.Nerve cells have developed: Nerve development is ongoing, but major brain structures are in place by the eighth week, with further sensory development at weeks 13-16.The sex can be determined: Differentiation of sex organs begins to occur between 9-12 weeks, allowing for determination of sex.Fat begins to develop: This occurs in the third trimester when there's rapid body growth and a substantial increase in body fat.The fetus starts to move: Uncontrolled movements begin as early as the sixth week, with more forceful movements occurring later on.

Write a scientific explanation that explains the genotype of the female and male rabbits.

Answers

The dad is this case would either have a BB or a Bb genotype and the mother would have a bb genotype. Their babies that are white would be bb and black would be Bb.

What is the main source of genes of every rabbit baby?

Every baby which gets one gene from its mother and the another from its father. These white babies will have received one b allele from their mother and one b allele from the father and the black babies might have gotten a b allelle from the mom and a B from their father.

The color between the two alleles A of the chromosomes are identical, while the color alleles B of the two chromosomes is different, the one that is a high appears darker and the one that is below appears clearer, so it means they are different, so they are heterozygous. An allele is one of the different forms that can take the same gene. Alleles occupy the same position (locus) on homologous chromosomes.

Final answer:

The genotypes of the mother and father rabbits that could produce this outcome in the phenotypes of their offspring are Bb and Bb. Both rabbits must be heterozygous for the black fur allele (Bb) in order to produce a ratio of six black babies to two white babies in their offspring.

Explanation:

The genotypes of the mother and father rabbits that could produce this outcome in the phenotypes of their offspring are Bb and Bb. The black fur allele (B) is dominant to the white fur allele (b). Since six of the babies were black and two were white, it means that the ratio of black to white offspring is 3:1, which is consistent with Mendel's Law of Segregation. In this case, both the mother and father rabbits must be heterozygous for the black fur allele (Bb) in order to produce this phenotypic ratio in their offspring.

if the man's genotype was AA then the phenotype of their children would be: 100% normal skin pigmentation.

Explanation:

I almost completely doubt that the answer is the second one since the mom was albino then he has to have the trait in him some where and so his genotype would be Aa. However, I gave you both answers just in case but trust me if u choose one I suggest the first one (50% 50%) because it is the most accurate considering his mom was albino.

Why is the tidal range smaller duringa Neap tide than it is during a Spring Tide?

Answers

Answer:

Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides. Hence, the range (difference in water level between high and low tide) is much larger in a spring tide than in a low tide.

Explanation:

Answer:

When this happens, the bulge of the ocean caused by the sun partially cancels out the bulge of the ocean caused by the moon. This produces moderate tides known as neap tides, meaning that high tides are a little lower and low tides are a little higher than average.
