Orca prey on sea otters. Sea otters are a predator of sea urchins. Sea urchins consume kelp. Kelp provides a habitat for many sea animals like prawns, crab and starfish.Marine biologists were monitoring a coastline of Africa. Over the course of a year, they counted the population sizes of various animals and charted it monthly in the following graph.What could be obersved about the population sizes at the end of the following year?A. The population of orca would increase.B. The population of kelp would increase.C. The population of crabs would decrease.D. The population of sea urchins would decrease.
Answers
The graph shows us that the population of sea otters is considerably decreasing, reaching really low rates. As orcas prey on them, it would be really difficult for the population of orca to grow, because there won't be enough food. Therefore, A is incorrect.
As the population of sea otters decrease, it is expected that the population of sea urchins increase, as there would be less predators (sea otters prey on sea urchins). Therefore, D is also incorrect.
As the population of sea urchins would increase in the following year, and knowing that they prey on kelp, it is expected that the population of kelp would decrease, as there will be more predators. Therefore, B is wrong too.
And as the population of kelp decreases, and knowing that kelps are the ones who provide habitat for crabs, it is expected that the population of crabs would decrease too. Therefore, the correct answer is C. The population of crabs would decrease.
Researchers have historically considered the human appendix to be a vestigial structure. What evidence, if true, would best disprove this claim?
A.
The appendix was used to help digest leaves in the ancestors of humans, but it appears to serve no function in modern humans.
B.
Chimpanzees also have an appendix, and humans and chimpanzees inherited the appendix from the same ancestor.
C.
Cows have an appendix to help them digest grass, but it evolved independently from the appendix found in humans.
D.
The human appendix helps to maintain the health of the gut, and arose fairly late in the evolutionary history of mammals.
Answers
The evidence that would best disprove the claim that the human appendix is a vestigial structure is option D. The human appendix helps to maintain the health of the gut and arose fairly late in the evolutionary history of mammals.
1. Option A suggests that the appendix was used to help digest leaves in the ancestors of humans but serves no function in modern humans. While this statement implies that the appendix may have had a purpose in the past, it does not directly disprove the claim that it is vestigial.
2. Option B states that chimpanzees also have an appendix and that humans and chimpanzees inherited the appendix from the same ancestor. This evidence supports the idea that the appendix has been conserved through evolution and suggests that it may serve a function in both species. However, it does not directly disprove the claim of the appendix being vestigial.
3. Option C mentions that cows have an appendix to help them digest grass, but it evolved independently from the appendix found in humans. This statement provides an example of another species with a functional appendix, but it does not specifically address the status of the human appendix.
4. Option D is the most compelling evidence to disprove the claim. It states that the human appendix helps maintain the health of the gut and arose fairly late in the evolutionary history of mammals. This suggests that the appendix has a beneficial role in humans and is not simply a vestigial remnant.
Therefore, option D presents the strongest evidence that would best disprove the claim that the human appendix is a vestigial structure.

1 What does the codon sequence on the mRNA strand determine?
A The gene sequence of the DNA
B The amino acid sequence of the polypeptide
C The codon that is signaled
D The signaling sequence
2 What portion of the DNA is also known as a gene?
A The coding sections
B The non-coding sections
C The mRNA strand
D The polypeptide sequence
Answers
1. The correct answer is B.
2. The correct answer is A.
The codon sequence on the mRNA strand determines the amino acid sequence of the polypeptide.
The coding section is the portion of the DNA that is also known as a gene. Genes are the functional units of DNA that provide the instructions for making proteins. They are composed of coding cells, also known as exons, that contain the information needed to build the polypeptide, and non-coding sections, also known as introns, that do not.
The codon sequence on the mRNA strand is translated by the ribosome during protein synthesis. Each codon, which is a sequence of three nucleotides, corresponds to a specific amino acid. The ribosome reads the codon sequence on the mRNA strand and adds the corresponding amino acids to the growing polypeptide chain. This process is called translation.
In DNA, genetic information is encoded in the sequence of nucleotides, which are the building blocks of DNA. Genes are specific segments of DNA that contain the instructions for making a specific protein. These instructions are encoded in the sequence of nucleotides within the coding sections of the DNA, also known as exons. The non-coding sections, also known as introns, do not contain instructions for making proteins, but they play important roles in the regulation of gene expression.

Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes. What are the main differences between these two processes, and what types of daughter cells produced by each?
Answers
Answer:
Hope this helps :)
Explanation:
Mitosis is the process by which cells duplicate.
Meiosis is a similar process which is just used to make reproductive cells such as eggs or sperm.
In mitosis, the cell DNA arranges into 46 chromosomes, duplicates, and then divides into two new cells.
In meiosis, the same duplication occurrs except four cells are created, each with only 23 chromosomes. (You know how you get half of them from each parent? This is so that the offspring have genetic variation.)
Another thing to notice about meiosis is that the cells are not identical like in mitosis, which simply duplicates them. Furthermore, in males all four sex cells are used as sperm but in females only one of these cells develops into an egg whereas the rest, called polar bodies, are reabsorbed into the body.
Answer:
Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.

Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.
How can the presence of one species in the same ecosystem assist another?A mutualism occurs when two species have a long-term relationship that benefits both of them (+/+ interaction). Some fungi, for example, create mutualistic relationships with plant roots. The plant may photosynthesize and gives fixed carbon to the fungus in the form of sugars and other organic compounds.
The presence of several species in an ecosystem balances it. The species in an ecosystem interact with one another in some way. For example, the existence of a plant species will offer food for the numerous herbivores found in an ecosystem. A predator may consume a variety of prey. As a result, the existence of diverse prey reduces the likelihood of a species becoming extinct in the ecosystem. As a result, all creatures in an ecosystem are dependent on one another in some way.

Basalt is a fine-grained, dark-colored igneous rock made primarily of the minerals plagioclase and pyroxene.
What are Basalt?The most prevalent rock on the surface of the Earth is basalt. Specimens range from dark green to brown to black in hue. Basalt is primarily made up of olivine, pyroxene, and plagioclase and is rich in iron and magnesium.
The majority of specimens are glassy, compact, and finely grained. They may also contain olivine, augite, or plagioclase phenocrysts and be porphyritic.
Basalt may have a texture that is coarsely porous due to holes caused by gas bubbles.

The BEST explanation of why engineering crops to be more tolerant of weedkillers enables farmers to stop or reduce tillage is that weeds can be killed with herbicides instead of through tilling.
The correct option is A.
What is tillage?Tillage is the process of mechanically preparing the soil by turning it over, which can be time-consuming, labor-intensive, and can disturb the soil structure.
By relying on herbicides instead, farmers can save time, reduce labor costs, and minimize soil disruption. This practice is often referred to as chemical weed control or chemical tillage and is a common technique used in modern agricultural practices.
