List two non-living (abiotic) forms of carbon in the cycle and give the chemical formula of each.

Answers

Answer 1

Answer: Two abiotic forms of carbon are CARBON DIOXIDE AND METHANE.
The element carbon is continuously been recycled in nature. The abiotic components of the carbon cycle refers to the non living part of the carbon cycle which has influence on the living part. Methane is a type of fossil fuel whose major component is carbon.
The chemical formula of carbon dioxide is CO2 while that of methane is CH4.

D. Over time, layers form and spread out over a wide area to form rock.

Answers

Answer:

Option (C)

Explanation:

Sedimentary rocks are formed due to the compaction and lithification sediments. For example, mudstone, sandstone, and shale.

Metamorphic rocks are those rocks that are formed when a sedimentary/igneous/other metamorphic rocks undergo changes in the pressure and the temperature conditions. Temperature and pressure are the main factors here. For example, slate, phyllite, schist, and gneiss.

Mudstone is a sedimentary rock that can convert into a fine-grained and foliated metamorphic rock called slate due to the increase in the temperature and pressure.

Hence, the correct answer is option (C).

C is the answer.

Metamorphic rocks is when a rock changes under time and lots of pressure.

Sedimentary is rocks made of sediment.

Igneous rocks are rocks that are made of magma.

Knowing this, C is closest to the definition of metamorphic rocks.

Which accurately describes meiosis II?In prophase II, the chromosomes line up in the middle of the cell.
In metaphase II, the chromosomes line up in the middle of the cell.
In prophase II, DNA is replicated and spindle fibers attach to the chromosomes.
In metaphase II, DNA is replicated and spindle fibers attach to the chromosomes.

Answers

In metaphase-II of meiosis, chromosomes are aligned in the middle of the cell. Option B is correct.

Meiosis:

It is a type of celldivision in which cells divide to form four haploid daughter cells. It is found in the germcells of organisms.

The process is completed in two phases,

In prophase- II, DNA is condensed into chromosomes and attached to the spindlefiber.

In metaphase, Chromosomes aligned into the metaphase plate.

Therefore, in metaphase-II of meiosis, chromosomes are aligned in the middle of the cell. Option B is correct.

Mitosis is used for almost all of your body’s cell division needs. It adds new cells during development and replaces old and worn-out cells throughout your life. The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less.

Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes—sex cells, or sperm and eggs. Its goal is to make daughter cells with exactly half as many chromosomes as the starting cell.

To put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs. When a sperm and an egg join in fertilization, the two haploid sets of chromosomes form a complete diploid set: a new genome.

Phases of meiosis

In many ways, meiosis is a lot like mitosis. The cell goes through similar stages and uses similar strategies to organize and separate chromosomes. In meiosis, however, the cell has a more complex task. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. But it must also separate homologous chromosomes, the similar but nonidentical chromosome pairs an organism receives from its two parents.

These goals are accomplished in meiosis using a two-step division process. Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis II.

Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

What does the moth do to avoid predators

Answers

Answer:

Moths make use of several self defending techniques to avoid predators.

Explanation:

Most people often confuse moth with butterflies, but moth are a different member of Lepidoptera, an flying insect. There are many ways through which moth protect themselves from predators.

Since moths are usually active during the night time, so they often hides in the day time from predators. Another technique that moths use is camouflage, where they can confuse the predators by blending into the surrounding. And when a predator us unable to see a moth, its life is saved. Apart from this, moths are even clever enough to trick bats by their strong detection power.
