Rasheeda made a model of a plant cell and labeled parts of the cell that are not found in animal cells. Which other part of the cell should Rasheeda label

Answers

Answer:

Cell wall, chloroplasts, plastids, and a central vacuole.

Explanation:

Rasheeda has to label cell wall, chloroplasts, plastids, and a central vacuole because these parts are not present in the animals cell. The outer boundary of animal cell is cell membrane whereas the outer boundary of plant cell is cell wall. The plant cell has chloroplast due to its function of making their own food with the help of sunlight so that's why it is not present in animal cell which can't make their own food. Plastid is also  absent in animals cell and present in plant cell which is responsible for manufacturing and storing of food. Both plant cell and animal cell has vacuole but different in their size and location in the cell.

Tell me a brief summary of what happens in meiosis

**will mark brainliest**

Answers

Hey There!_____________________________________ANSWER:[tex]\Huge{\textbf{MEIOSIS:}}[/tex]

Meiosis is a special type of cell division, which occurs only in the germ cells during the process of development and maturation to form gametes. It consists of two successive cell divisions,

Meiosis 1 : First meiotic division, that reduces the NUMBER of chromosomes i.e. the parent cell is diploid(46 Chromosomes) and the daughter cells are haploid(23 Chromosome). It also causes genetic variation in the haploid by cross linkage.Meiosis 2 : Second meiotic division (Meiosis II) starts with two haploid parent cells and ends with four haploid daughter cells. Meiosis 2 like Meiosis 1, does not reduce the NUMBER OF CHROMOSOME that means the forming 4 daughter cells are haploid and their number of chromosome remains the same as the parent. BUT Haploid cells that go into the meiosis 2 have MORE AMOUNT OF CHROMOSOME THAN USUAL, thus MEIOSIS 2 REDUCES the amount of chromosome rather than the number of chromosome.

The DNA of the primitive germs cells is replicated prior to the meiosis 1 only and there is no replication of DNA before Meiosis 2. The four final cells reulting from the two meiotic divisions are not only haploid(i.e. containing 23 chromosome) but they are also containing 1n amount of DNA so that when the gametes fuse together forming a zygote, both the amount and number of chromosome and DNA remains SAME.

_____________________________________[tex]\huge{\text{Why is Meiosis Important?}}[/tex]

Meiosis is essential for the sexual reproduction of eukaryotic organisms because it enables genetic diversity through recombination, and the repair of genetic defects.

It contributes in genetic reassorment which ensures the genetic diversity in the offsprings. The genetic reassortment takes place by following two mechanisms:

During the prophase of meiosis 1, crossing over of genetic material between the homologous maternal and paternal chromosomes takes place which causes exchange of DNA fragments between the chromosome resulting is genetic diversity.During the anaphase of the first meiotic division, there is random distribution of maternal and paternal homologous chromosomes among the daughter cells which are produced as a result of meiotic division._____________________________________Best Regards,'Borz'

Answers

Answer:

The correct answer is - Humans should leave primary growth forests and their residents intact, and ensure that secondary growth forests have a chance to regrow.

Explanation:

Humans should not clear the forest at any cost as cutting the forest affect the flora and fauna of the forest and residents of the forest lose their habitat. The clearing or affecting the habitat leads to an increase in the global warming as there is increase in the carbon dioxide gas.

Humans need to intact the primary growth and flora and fauna of the ecosystem. It also need to be ensure that forests have cahnce to regrow. It should be also put in consideration that inhabitants should be protected.

How do gravity and inertia work together in our solar system?

Answers

Answer:

They work together to keep things in orbit.

Explanation:

Gravity pulls things in, while inertia says that all celestial objects will try their best to continue forward. The results in the orbiting of celestial objects, like the Earth, around other celestial objects, like the Sun.

Answer:

The gravity of the sun and the planets works together with the inertia to create the orbits and keep them consistent. The gravity pulls the sun and the planets together, while keeping them apart. The inertia provides the tendency to maintain speed and keep moving.

b. commensalism-
c. parasitism -
d. predator/prey -
e. competition -

Answers

Answer:

mutualism -Both species benefit

commensalism- One species lives with, on, or in another species (the host). The host species neither benefits nor is harmed from the relationship. The species that lives on the host is benefited.

parasitism - One species (the parasite) lives with, on, or in a host species, at the expense of the host species. Unlike in predation, the host is not immediately killed by the parasite, though it may sicken and die over time.

predator/prey -One species (the predator) hunts and kills another species (the prey)

competition -The struggle among organisms for the same limited resources in an ecosystem

Watch the seven minute video on the "Mystery of the Buffalo boom" on you tube. Write a reflection on how scientists used their reasoning skills to make a claim about causes of the "buffalo boom".

Answers

Answer:

In the "Mystery of the Buffalo boom" scientists first try to find the answer in the two most common things that can affect a population of animals.  Food and predators.

First, they studied the buffalos' food supply, grass. They found that there has not been an increase in it so that the number of buffalos multiplied.

Then they studied the predator's population, and they found that there was not a decrease in the number of them that could affect the buffalos increasing numbers.

As the two main things that controlled a population were not affected, they had to find other causes. The next thing that they studied were historical facts about buffalos and diseases. Scientists discovered that a virus that affected cows had impacted these animals too, which was the cause of a considerable decrease in the buffalo's population many years back.

Due to the drastic impact that the rinderpest had on cows, a vaccination plan was implemented. As the cows now were protected against this virus, the virus could not reproduce as it did, ending the spreading of this disease in cows. As a consequence, the buffalos were no longer infected, and their population grew thanks to the vaccination plan.

In conclusion, when the most common things that can affect a population are not the cause, we have to look into the past and find what has changed and how it impacted the animals. It is using logical thinking skills to determine what has changed and what that change made.

Explanation:

In the video "Mystery of the Buffalo boom" the ecologist Tony Sinclair found an abnormal buffalos' number in Tanzania. As the increase in the buffalos' population was something unusual, he knew that something had changed, but he did not know what. Sinclair, with other scientists, used their reasoning skills and thought that the two most logical things that can affect a population are food and predators. When they studied these two variables, they found out that they were not the problem. The next step was to look for past events that impacted buffalos. They found out that a virus, which directly affected cows but also buffalos, had been erased from the Earth thanks to a vaccination plan. As a result, the disease spreading between cows stopped, and as a consequence, it also stopped between buffalos.

We can see that everything is connected and that by using reasoning skills and logic, scientists could determine what happened.
