Plzz Help!! Do not do it for the points plz i really need help on this

Answer:

A

Explanation:

Each polyp makes its own cup-shaped skeleton called a calyx ("KAY-lix)" from limestone (calcium carbonate). The base of the calyx is called the basal plate, and the outer walls of the calyx are called the theca ("THEE-kuh")

Answer:

I'm pretty sure it's A

Explanation:

coral skeletons are biocomposites (mineral+organics) or calcium carbonate

Answer:

Because it takes a very long time and an interesting mindset.

Explanation:

People don't really have an explanation for the things that we do they just suddenly build up inside us

Answer:

This is because the mutated gene responsible for Duchenne is located in the X chromosome. Girls have two X chromosomes, meaning that the body usually inactivates the chromosome that carries the mutation. The female will carry the mutation, but manifest little to no symptoms of the disease.

I hope that this helped you ;)

Explanation:ture,as the body gets CD the body takes that and gives it to the lungs which than turns the CD into  O2 which makes glucose.

Answer:

B and D

Explanation:

Human behaviors do not affect the entire evolution of every lifeform that has existed, therefore, A is FALSE

Carbon dating is commonplace in figuring out how old a lifeform could be, therefore, B is CORRECT

Blood proteins are commonly known to not last long and decompose fast, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE

For D, I kinda forgot most of my explanation, but I remember that it's correct, as I got the question correct on the assignment.

The carbon dating of fossils and comparison of homologous structures are techniques besides molecular clocks used by scientist to calculate the rate at which a stretch of DNA changes.

So, option B and D are correct one.

Human behaviors do not affect the entire evolution of life of organism that has existed, therefore, A is FALSE

Carbon dating is commonplace in figuring out how old a life of any organism, therefore, B is CORRECT

Blood proteins are commonly known to not last long and decompose faster, so fossilization of blood tends to not happen, plus it's next to impossible to tell what species had that genetic data, therefore, C is FALSE

By comparing of homologous structures we determine nucleotide sequence exchanged between two similar or identical molecule of DNA. So, option D is correct

Answer:

Genotypic probability = 1RR: 2Rr: 1rr

Phenotypic probability = 1Red: 2Pink: 1white

Explanation:

This question involves a single gene coding for skin color in snapdragon plants. The alleles are incompletely dominant over one another and hence, produce an intermediate pink phenotype.

According to this question, two pink/heterozygous snapdragons were crossed i.e. Rr × Rr. Each parent will have gametes R and r. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Genotypic probability = 1RR: 2Rr: 1rr

Phenotypic probability = 1Red: 2Pink: 1white

Answer:

A.

Explanation:

The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

Answer:

Explanation:

In s phase, the dna replication take place in interphase, The dna in the nucleus replicates so that each chromosome consists of two identical chromatids, then in mitosis they are pulled apart in anaphase in which both cells have half of the chromosomes, in Telophase each chromatid contains one dna molecule, which will replicate itself during interphase before the next division.

The new cells are similar from the original ones in interphase as these will have same amount of DNAs.

The interphase phase of the cell cycle is where the majority of the life of a typical cell occurs.

Interphase is the cell's "daily living" or metabolic phase, during which it obtains and metabolizes nutrients, grows, replicates its DNA in preparation for mitosis, and performs other "normal" cell functions.

The cell cycle's longest phase is interphase. This is the stage at which the cell grows and copies its DNA before entering mitosis.

Chromosomes align, separate, and move into new daughter cells during mitosis. Because the prefix inter- means "between," interphase occurs between mitotic (M) phases.

In interphase, the new cells are similar to the original ones because they have the same number of DNAs.

Thus, this can be the similarity between these two.

Answer:

Your answer is that mining activities increase the volume and rate of exposure of sulfur-containing rocks to air and water, creating sulfuric acid and dissolved iron. This acid run-off dissolves heavy metals such as copper, lead and mercury which leach into ground water aquifers and surface water sources, harming humans and wildlife

Answer:

Explanation:

The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.

Answer:

esophagus

Explanation:

the esophagus is the pipe/muscle that leads to your stomach

Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.

The digestive system, sometimes known as the gastro-intestinal tract, includes the oesophagus (gullet) (GI tract). An oesophageal tube is made of muscles. It joins the mouth with the stomach.

The oesophageal walls contract together as you swallow food (contract). This causes the food to travel from the mouth to the stomach.

The diaphragm is a layer of muscle located below your lungs. It facilitates breathing. The majority of your oesophagus is located in your chest above the diaphragm.

Therefore, Choking on food is most likely caused by an interference with the proper functioning of the oesophagus.

Answer:

C. P -› F1 -› F2

Explanation:

In genetics and breeding, the following symbols represents the following:

P => parental

F1 => First filial generation

F2 => Second Filial generation

The crossing of two parent plants (P) produces offspring that is tagged the first filial generation (F1). The next cross involving the F1 offspring produced second filial generation (F2).

Therefore, the correct sequence is:

P -› F1 -› F2

Explanation:

Nitrifying bacteria convert the most reduced form of soil nitrogen, ammonia, into its most oxidized form, nitrate(Science direct).

Nitrifying bacteria converts ammonia to nitites and finally to nitrates in the soil.

Hence, when 30 g of ammonia, nitrate and nitrite are added to a soil sample in the presence of nitrifying bacteria; the concentration of ammonia decreases over time while the concentration of nitrite and nitrate increases over time.

ammonia stays the same

nitrates decrease

nitrates increase

Volcanic Eruption

Explanation:

(I also know because I took the quiz) The volcano is the one that rapidly changes. It can erupt any time.

Forest Succession is slower than a volcanic eruption. It might take years for the trees in a forest to grow and for the population of animals to get there. It has to be just right, it needs all the plants and animals for it to be a forest, well not all of it but most of it.

Decomposition is also slower than a volcanic eruption.

Tree growth takes a long time. It might not even be a full tree until years later. It also takes time and water.
