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.

A cell can replicate itself independently. Hence, they are known as the building blocks of life.

Cells provide structure and support to the body of an organism.The cell interior is organised into different individual organelles surrounded by a separate membrane.The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth.Every cell has one nucleus and membrane-bound organelles in the cytoplasm.Mitochondria, a double membrane-bound organelle is mainly responsible for the energy transactions vital for the survival of the cell.Lysosomes digest unwanted materials in the cell.______________________________

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.

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.
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.
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.

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.

one copy, four copies
Answer:
B. one copy, two copies
Explanation:
Haploid is 23 chromosomes, so there is one copy of each human chromosome while diploid is 46 chromosomes, so there are two copies of each human chromosome.

millions of years
Answer:
we must look at billions of years
When considering the entire period of time during which life on Earth has been evolving, we must look at: D. billions of years.
Evolution can be defined as a process of gradual change in the characteristics of various species of living organism over several generations.
Basically, these characteristics refer to gene expressions that are typically transferred from parent organisms to their offspring or successive generations.
The earliest life forms known to humans existed about 3.7 billion years ago and they are microscopic organisms (microbes) whose fossils were found on rocks.
In conclusion, when you are considering the entire period of time during which life on Earth has been evolving, you must look at billions of years.
