Answers

Answer 1

the answer is D, I hope it helps

Answer 2

Answer:

The answer is D) Marine organisms die because oil stops oxygen from entering the water.

Explanation:

The oil spill results in the death of many marine beings, due to the contaminants of the oil compounds that are tremendously toxic. Due to the oil film, the oxygen content in the water is reduced, which causes the asphyxiation of the fish, since they need oxygen to live, which comes from the water, that by the gills, retains the present oxygen and distributes it through the circulatory system through the body.

I chose this because it's the only one not explained about these types of rocks and they aren't used a lot. (this just my opinion so you don't have say im right).

Answer:

D. They are very productive agriculturally.

Explanation:

Laterite soils are of rusty red color. Their red appearance is because of the fact that they have very high content of iron and iron oxide. They are formed in wet tropics naturally. They are not at all suitable for agriculture because they are highly acidic in nature. Not only this but also, they have very low water retention capacity. These two properties make them unsuitable for cultivation.

What is the result of meiosis II?

two diploid daughter cells
four haploid daughter cells
two haploid daughter cells
four diploid daughter cells

Answers

I think two haploid daughter cells

Answer: Option B

Explanation:

In some species there is a very small interphase, or interkinesis before the cell enters in the the process of meiosis II.

The two daughter cells that are produced after meiosis I go though the process of meiosis II. During the process of meiosis II the two sister chromatids which lies in daughter cells separate, resulting in formation of four haploid daughter cells. This process is similar to mitosis.

Stages of mitosis and what happens in each stage.

Answers

There are 4 stages in Mitosis...
Prophase:
It is the first phase in which the chromatin coil to become chromatids, and those chromatids pair up and the nuclear membrane surrounding them dissolves. The centrioles move to each end (pole) of the cell.
Metaphase:
Where the paired chromatids align in the centre of the cell and spindle fibres attach to them at the centromere.
Anaphase:
The centrioles act as anchors, tearing the paired chromatids away from each other using the spindle fibres. Each paired chromatid moves to either (the opposite) end of the cell.
Telophase:
Where the chromatids elongate to form chromatin, and a nuclear membrane begins to form around the chromatin at each end of the cell. Cytokinesis occurs in this stage as the cell separates into two daughter cells. In animal cells, there is cleavage as the two cells are starting to separate. In plant cells, a plate begins to form.

Explanation:

Various enzymes function most efficiently under different sets of “optimal” conditions. explain why this is the case.

Answers

An enzyme is protein and it needs to maintain its 3D structure as the enzyme work like "lock and key". A little deformation to the enzyme structure can disable its functions.
Protein is prone to denaturation. Condition like pH and temperature can affect the protein and cause an alteration to its structure. Higher temperature should speed up the reaction but too high temperature might damage the enzyme. So, the "optimal" condition would be the condition where the enzyme structure is not altered.

Enzymes work efficiently under specific conditions due to their adaptation to different cellular environments and factors like pH and temperature. Variations in enzyme activity depend on environmental factors and substrate concentration. These factors ensure optimal biochemical reactions in cells.

Enzymes are biological catalysts that function most efficiently under specific optimal conditions. Several factors contribute to this phenomenon:

Enzymes are adapted to their cellular environments, so different cells have varying enzyme needs. For example, stomach cells require different enzymes compared to fat storage cells or nerve cells.Environmental factors like pH, temperature, and salt concentration significantly impact enzyme activity. For instance, human pathogens have enzymes that work best at 37°C, while microbes in hot springs have enzymes optimized for high temperatures.The presence of dietary intake influences enzyme activity in digestive organs, where more enzymes are needed to process nutrients after a meal.Enzyme activity is also influenced by substrate concentration. Increased substrate levels enhance enzyme activity up to a saturation point.

These conditions ensure that enzymes efficiently catalyze reactions necessary for cellular functions to adapt to their varying environmental and physiological requirements.

Answers

Final answer:

The lipid and protein compositions of membranes in organelles within the endomembrane system are determined by the specific functions of each organelle. Each organelle requires a unique lipid and protein composition to support its function.

Explanation:

The differences in the lipid and protein compositions of the membranes in various organelles in the endomembrane system are largely established by the specific functions and roles of each organelle. Each organelle has unique requirements for lipid and protein composition to support its function. For example, the endoplasmic reticulum (ER) is responsible for lipid synthesis, so it has a higher concentration of lipids compared to other organelles. The Golgi apparatus, on the other hand, is involved in protein modification and sorting, so it has a higher concentration of specific proteins.

Once a pathogen (damaging cells/harmful) is detected within the body, the immune system deploys white blood cells to defend the host and eliminate the threat. The Immune System acts as our body’s security system.

Final answer:

The immune system is a complex network of cells, tissues, and organs that work together to protect the body from harmful pathogens. It includes key components such as white blood cells, antibodies, and the complement system.

Explanation:

The immune system is a complex network of cells, tissues, and organs that work together to protect the body from harmful pathogens, such as bacteria, viruses, and parasites. its components are -

White blood cells: These cells are the main players in the immune system. They include neutrophils, macrophages, and lymphocytes.Antibodies: Antibodies are proteins produced by B cells and play a critical role in identifying and neutralizing harmful pathogens.Complement system: The complement system is a group of proteins that work together to enhance the immune response.

Based on the table, which domains contain only one cell type? Fungi and Eukarya Bacteria and Archaea Eukarya and Fungi Plantae and Bacteria

Answers

The right answer is Bacteria and Archaea.

A prokaryote is a unicellular organism (bacterium, cyanophyceae) that does not have a nucleus. The DNA is circular, usually unique and grouped in a nucleoid. This region contains the genetic material, but is not separated from the rest of the cell. This is precisely what separates the prokaryote from the eukaryote.

Archaea are prokaryotic unicellular microorganisms. Archaea, which often look like bacteria, have long been regarded as specific extremophile bacteria, until phylogenetic research on prokaryotes, begun in 19652, culminated in the publication in 1977 of a phylogenetic tree based on the sequences of the ribosomal RNA genes of the organisms studied, a tree in which the prokaryotes were split into two distinct domains, that of the bacteria and that of the archaea.

Final answer:

The domains that contain only one cell type are Bacteria and Archaea as all organisms within these domains are unicellular.

Explanation:

In the context of biological classification, cell type is one way to categorize living organisms. The question refers to 'domains', one of the highest taxonomic ranks in this system. In terms of cell type, all organisms in the domains Bacteria and Archaea are unicellular, meaning they only have one cell type. However, other domains like Eukarya include both unicellular organisms (like some fungi and protists) and multicellular organisms (including animals, plants, and most fungi).

Answers

Final answer:

A liger, as the hybrid offspring of a male lion and a female tiger, is sterile, exemplifying a biological phenomenon where the mixed chromosomes from parents of two different species produce non-viable gametes.

Explanation:

The offspring of a male lion and a female tiger, known as a liger, exemplifies a phenomenon of hybrid sterility. Male ligers are unable to produce offspring. This is due to the fact that the parental species, lions and tigers, have a different number of chromosomes which, when combined, create a mismatched set. Although the ligers and tigons have a functional set of genes, the gametes produced during meiosis do not have a complete set of genes necessary for survival in subsequent generations. This biological concept is seen in other animal hybrids as well, such as mules and hennies, which are the sterile offspring of horses and donkeys. Understanding these hybridization outcomes is vital for conservation and biology.
