elect all statements that accurately describe the structures or functions of mitochondria. Mitochondria are the sites of aerobic metabolism. Mitochondria have a permeable inner membrane and an impermeable outer membrane. Mitochondria regulate apoptosis. Mitochondrial DNA is packaged with histones. The configuration of mitochondria does not change. Mitochondria are included in the endomembrane system.
Answer:
The correct statements are -
Mitochondria are the sites of aerobic metabolism
Mitochondria regulate apoptosis.
Explanation:
Mitochondria is one of the eukaryotic cell organelles that are double membrane and plays important role in the different function of the cell. The main and major function of the mitochondria is aerobic metabolism that includes aerobic respiration where glucose converts into carbon dioxide and water with releases a high amount of energy in the form of ATP.
These also plays important role in programmed cell death or apoptosis it activates apoptosis by releasing protein by the inner and outer membrane. The inner membrane of mitochondria is impermeable and allows through transporters and outer membrane non-specifically permeable to low molecular substances. Mitochondrial DNA lacks histone protein and TFAM, an HMG-like protein involved in the process.

Is the following sentence true or false? Liquid magma is formed when small amounts of mantle rock melt?
Answer:
Absolutely True!
Explanation:
Explain the relationship between mutations, adaptations,
natural selection, and extinction.
Answer: A mutation results in different alleles for a gene and these different alleles will cause adaptations that may be favorable or unfavorable. If no species in an area has adaptations suited for the environment after it changes, extinction will occur.Adaptations result from random mutations in the genes of organisms. Depending on the environment, these adaptations may be favorable or unfavorable. If an adaptation is favorable, it is selected by nature and, over time, more and more organisms in a population will have it. If the environment changes so much that the adaptations of a species are no longer enough for the species to survive, extinction will occur.Mutations is very different because it results in different alleles for a gene.Adaptations is where an animals ADAPTS to an environment.Natural selection consists of overproduction,variation, favorable adaptations.extinction is when a species completely disintegrates.

Explanation:
These weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them. For a few years, the former relies on manually removing the woods, but that is labor intensive and limits how much crop he can grow. The farmer decided to change his crop to genetically modified soybeans that are herbicide resistant. This allows the farmer to use chemicals to remove the weeds. With this GM soybean, the chemical kills the woods but does not harm the crop. For many years this works, and allows the farmer to expand his farm and grow more soybeans. But then, one of the farmer's fields has a large weed plant remaining after the field has been sprayed with herbicide
1. Which of the following is the likely reason the weed has remained?
a. The weed needed to be resistant in order to survive, so it became resistant
b. A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
2. Which of the following is likely to happen if that weed stays in place?
a. The trait will spread to nearby weeds
b. The weed will survive long enough to reproduce
c. In time, the herbicide will no longer be effective on that field.
Answer:
1) A mutation appeared in one weed plant that made that weed not susceptible to the herbicide ( B )
2) The weed will survive long enough to reproduce ( B )
Explanation:
1) The most likely reason the weed remained is : A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
The weed plant must have undergone some mutation in order to be resistant to the herbicide which would kill the weed before now
2) The most likely thing that will happen if the weed stays in place in that farm is : The weed will survive long enough to reproduce
The trait or mutation of the weed cannot just spread to other weeds nearby it can only spread by reproducing more weeds of same mutation
Assume that you discover a new human gene that you believe is located on the Y chromosome although not in the region (pseudoautosomal) of the Y that is homologous with part of the X chromosome. How would you map this gene with respect to the other genes on the Y chromosome
Answer:
by performing a bioinformatic analysis in order to discover Y chromosome-linked mutations associated with defective phenotypes. In this case, it is expected to discover two or more loss of function mutations located in the coding region of the target gene on the Y chromosome in different males, and then associate such mutations with altered phenotypes caused by the inactivation (loss of function) of this gene
Explanation:
The genes located on the Y chromosome exhibit a uniparental mode of inheritance (i.e., these genes are only transmitted from father to their sons). This situation makes difficult to map the target gene since recombination does not occur for genes that are only located on the Y chromosome, hampering the development of a linkage map containing this gene. In this case, it is possible to directly associate genetic mutations located at the same genomic region (locus) on the Y chromosome with a particular altered phenotype in males carrying these mutations, which can be in principle associated with the inactivation of the target gene (loss of function mutations) in these individuals.

Woodpeckers and squirrels fight for nesting rights in the same holes and spaces in trees, while the lions and cheetahs of the African savanna fight for the same antelope and gazelle prey. Which of the following statements about these relationships is accurate?
A. These are examples of competition because the organisms are fighting for resources.
B. These are examples of predation because the organisms are trying to take each other’s food and homes.
C. These are examples of predation because lions and cheetahs eat woodpeckers and squirrels.
D.These are examples of competition because no organisms are helped or harmed.
Answer:
a
Explanation:
both of the cases the organisms are fighting for a resource
A. These are examples of competition because the organisms are fighting for resources.
How Competition and predation are two different types of relationships ?Competition and predation are two different types of relationships that can exist between different organisms in an ecosystem. Competition occurs when two or more organisms are fighting for the same resources, such as food, water, or shelter.
This can occur within or between different species. In the example given in the question, woodpeckers and squirrels compete for nesting rights in the same holes and spaces in trees, while lions and cheetahs compete for the same antelope and gazelle prey.
On the other hand, predation occurs when one organism (the predator) hunts, kills, and consumes another organism (the prey). This type of relationship is often seen between carnivores and herbivores, or between animals and insects. In the example given in the question, lions and cheetahs are predators that hunt and consume antelope and gazelle prey.
It is important to note that in both competition and predation, one organism may benefit while the other is harmed.
For example, in predation, the predator benefits by getting food while the prey is harmed by losing its life. In competition, one organism may gain access to the resources while the other loses out, which can affect their ability to survive and reproduce.

Hydra:
Reproduction by budding in Hydra.
Amoeba:
Reproduction by binary fission in Amoeba.
Hydra:
Budding means sexual reproduction in which a new organism develops from a bud in the parent.
Amoeba:
Binary fission is the type of asexual reproduction in which the parent divides to give rise to two daughter organisms.
Hydra:
In budding process, bud is simply an outgrowth of cells at one particular site.
Amoeba:
The parent replicates its genetic material and divides it equally between the two daughters in binary fission.
Hydra:
The bud or the newly formed organism remains attached to its parent until maturation.
Amoeba:
Both the cytoplasm and the nucleus of the parent divides into two.
1. Which of the following events is not a source of genetic variation in eukaryotic organisms?
J. Mutation
K. Independent assortment
L. Mitosis
M. Fertilisation
Answer:
Mitosis
Explanation:
Mitosis is not a source of genetic mutation because it take place mostly in the somatic cells. This is because it does not lead to the production of gametes . In mitosis, the parent cells divide into two daughter cells and each daughter cells are genetically identical to the parent cell because they carry the same number of chromosomes as the parent cell. There is no genetic variation in this.
