Answer:

The First and Third one for sure

Explanation:

Carnivores eat primary consumers as well as other carnivores if I'm not wrong, which would make them secondary or higher consumers.

Also, herbivores eat producers, which are plants and stuff and basically organisms that make their own food, which would make them primary consumers.

Why coocked food spoil fast but uncocked food spoil slowly

Answers

Sorry if this doesn’t help but here’s what I found:

Cooked food is bruised, denatured and cut up so that more surface area of the food is available to air and bacteria. Naturally, bacteria has an advantage here compared to an unprocessed food. This is why a cooked food can be more susceptible to spoilage than an uncooked food.

Answer:

My answer is the genotypes are BB, Bb, Bb, and bb.

Explanation:

I attached a photo of the punnet square after crossing the genotypes Bb and Bb.  Crossing the B on top with the B on the side results in the genotype BB.  Crossing the b on top with the B on the side results in Bb.  The genotype that results is written in the box that connects the row and the column (such as top row and left column results in BB).

The pedigree below shows the inheritance of a dominant allele of a gene in a family over several generation. Circles represent females and squares represent males. Shaded symbols indicate individuals carrying the allele. The pedigree suggest that the gene is on a nuclear chromosome, and not on a mitochondrial DNA, because A) mitochondrial genes are not heritable B) mitochondrial mutations cannot produce dominant traits C) maternal mitochondrial mutations are inherited by all of a mother's offspring D) mitochondrial DNA is circular, whereas chromosomal DNA is linear

Answers

Complete question:

You will find the pedigree in the attached files

Answer:

The correct option is C) maternal mitochondrial mutations are inherited by all of a mother's offspring.

Explanation:  

Mitochondrial inheritance is one of the ways in which a disease or a trait might be inherited from the maternal line.

Most of the DNI is located in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly carry mitochondria, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this DNI, the whole progeny of the mutated woman will be affected, as they will get the mother´s mitochondria carrying the mutation. On the contrary, if there is a man affected by a disease caused by a mutation in mitochondrial DNI, non of their descendants will get the disease.

In the exposed pedigree, we can see that the mother is affected by the disease, but the couple had two daughters, and only one of them was affected, while the other one was not. This tells us that the mutation occurred on a nuclear chromosome. If the mutated allele was in mitochondria, both daughters would be affected.

The pedigree suggests that the gene is on a nuclear chromosome, and not on a mitochondrial DNA because maternal mitochondrial mutations are inherited by all of a mother's offspring (Option C).

Mitochondrial DNA (mtDNA) is a special type of genetic material that exhibits a matrilineal inheritance pattern.

In consequence, all genes (and mutations) contained in mtDNA will pass from the mother to her offspring.

It is for that reason that mtDNA is widely used in evolutionary studies (we can trace matrilineal lineage from mtDNA).

In conclusion, the pedigree suggests that the gene is on a nuclear chromosome, and not on a mitochondrial DNA because maternal mitochondrial mutations are inherited by all of a mother's offspring (Option C).

Answers

Answer: Japan's economy depends heavily on industry and must be modern to be competitive.

Explanation:

Capital goods are referred to as the physical assets which are utilized during production process and they're simply used to produce other goods. Examples of capital goods are machinery, buildings, vehicles etc.

Explain how the sugars, phosphates, and nitrogenous bases in one strand of DNA connect to a complementary strand during replication

Answers

Answer: One strand of DNA binds to another via base complementarity.

Explanation:

The two strands of the DNA double helix are connected through nucleotides. There are hydrogen bonds between the nitrogenous bases. Each nucleotide has a sugar, nitrogenous base and phosphate group. The phosphate group and sugar forms the backbone of the DNA double helix. The nitrogenous base form pairing with each other via base complementarity. Purines are adenine and guanine and pyrimidine are cytosine and thymine these are nitrogenous bases. The adenine bonded with thymine via two hydrogen bonds and cytosine with guanine with three hydrogen bonds. These nitrogenous bases help in replication process.

The two strands of DNA are actually connected by hydrogen bonds (H-bonds) between the nitrogenous bases.

There are 2 hydrogen bonds between adenine and thymine, and 3 hydrogen bonds between cytosine and guanine.

Why are sugar-phosphate and nitrogenous bases important to DNA molecules?

The sugar-phosphate backbone is a significant component of DNA's double helix structure.

The structure of DNA is tied to its function. The pairing of the nitrogenous bases that are connected to the sugar-phosphate backbone play a key role in the ability of DNA to store and transfer genetic information.

Thus, base complementary is the reason.

Which of these processes does not occur as part of the cell cycle in animal cells?

1) Mitochondrial DNA is released into the cytoplasm

2) Two identical copies of chromosomes are produced

3) Cell growth and mRNA synthesis occur

4) Nuclear DNA is replicated

Answers

The cell cycle is an essential process of growth and function. It has many phases which divide the genetic material and the cytoplasmic organelle equally into new cells. The cell cycle is crucial for survival.

Option 1) Mitochondrial DNA released into the cytoplasm is the process that does not occur in the animal cell cycle.

Cell cycle steps in animals can be explained as:

In the animal cell cycle during the synthesis step, the genetic material replicates to produce two identical chromosomal groups.

The cell divides to grow and the processes of central dogma including mRNA synthesis and protein formation occur.

Mitochondrial DNA does not get released in the cytoplasm but remains sustained in the mitochondria structure.

Therefore, mitochondrial DNA is not discharged into the cytoplasm.

O Liquid water from the Earth's surface is evaporated into a gaseous form and enters the atmosphere as water vapor.

Answers

Answer:

it's O n2. So, The most important source of water in the atmosphere is conduction...

Explanation:

Hope that helps! (Btw I did this test and got it correct)

The statement "The most important source of water in the atmosphere is conduction from the oceans" is not correct.

The most important source of water in the atmosphere is evaporation.

What is  evaporation?

Evaporation is a process through which a liquid transforms into a gas. It's a type of vaporization that occurs specifically at the surface of a liquid. Whenever a liquid gets heated the molecules, near its surface gain energy. Become more active. These energetic molecules tend to collide with each other resulting in some of them escaping from the liquids surface and entering the gas phase.

In terms of sourcing water for the atmosphere, evaporation of water from the Earths surface plays a role. Although water vapor does come from the oceans through conduction it's not the source that we rely on.
