In South America near the Andres Mountains and in Africa near Mt. Kilimanjaro, the climate is cold. Why do you think this is so?
The cold climate near the Andes Mountains in South America and Mt. Kilimanjaro in Africa is primarily due to their high elevations. As air rises over mountain ranges, it cools and loses moisture, resulting in lower temperatures and arid conditions on the leeward side of the mountains.
What is the height of Mt. Kilimanjaro?Mount Kilimanjaro is the highest peak in Africa, rising over 19,000 feet above sea level. The mountain's height and location near the equator result in a unique climate that includes freezing temperatures at the summit despite its proximity to the hot and humid tropics below.

Which structures can be found on a protist but not on a fungus?
Answer:
See the answer below
Explanation:
First, there is a need to know that protists are unicellular, animal-like living organisms while fungi are unicellular/multicellular, achlorophyllous, and heterotrophic decomposing organisms.
A typical protist may have a plant-like cell wall or just an animal-like cell membrane without a cell wall. This is unlike fungi whose structure includes a rigid, chitin-containing cell wall.
Most protists also have locomotive structures that enable them to be motile. For example, the amoeba has pseudopodia, the paramecium has cilia, while the euglena has flagella. Fungi generally are immotile, that is, they do not have any locomotive structure that enables them to move.
Some protists have two vacuoles - contractile and food vacuoles - which assist them in essential functions such as osmoregulation and nutrition. Unicellular fungi such as yeasts only have a single vacuole.
Some protists such as the euglena have chloroplast which enables them to photosynthesize in addition to other forms of nutrition. Fungi generally, however, are achlorophyllous. They lack chloroplast/chlorophyll in any form.

Why are white-eyed female fruit flies so rare in nature?
A. White-eyed females are not rare.
B. The allele for white eyes was nearly removed from the gene pool.
C. Females must inherit two copies of the recessive allele.
White-eyed female fruit flies so rarely in nature because females must inherit two copies of the recessive allele. Therefore, option C is correct.
Why are white-eyed female fruit flies so rare in nature?The gene for eye color in fruit flies is located on the X chromosome, and there are two possible alleles: one for red eyes (dominant) and one for white eyes (recessive).
Male fruit flies have only one X chromosome, so if they inherit the white-eyed allele, they will have white eyes. However, females have two X chromosomes, so they must inherit two copies of the white-eyed allele to have white eyes.
Because the white-eyed allele is recessive, it is much less common than the red-eyed allele in the gene pool. In nature, white-eyed female fruit flies are rare because they must inherit two copies of the recessive allele from both parents. Thus, option C is correct.

Explain how different links can show a relation between two species. Describe evidence that shows other correlations and causations between the species.
Different links show relationships between two species. In the scientific world, there are three types of links, including mutualism, parasitism, and commensalism.
Mutualism is a relationship in which both species benefit. Parasitism is where one species benefits, and the other is harmed. Commensalism is a relationship in which one species benefits, and the other is not harmed or helped.One example of a mutualistic relationship is the bee and flower relationship. Bees collect nectar and pollen from flowers for their food, while at the same time, the bee helps in pollination. The bee gets food from the flower, and the flower is pollinated. This is a mutualistic relationship. A parasitic relationship is the relationship between tapeworms and humans. Tapeworms live inside the host and get their food from the host, thereby, causing harm to the host. Evidence that shows correlation and causation between the species includes physical changes in the organism or adaptations to the environment. For example, an animal that feeds on a certain plant may evolve to have a longer tongue to reach the nectar of that plant. In summary, different links show relationships between species, including mutualism, parasitism, and commensalism. The evidence for the correlation and causation between species includes physical changes or adaptations in the organism or environment.For more questions on species

uses of biotechnology in washing powder making
Answer:
Here are some uses of biotechnology in the production of washing powders:
Enzymes: Enzymes are commonly used in washing powders to enhance the cleaning efficiency and remove various types of stains. Proteases, amylases, lipases, and cellulases are examples of enzymes used in washing powders. These enzymes break down protein-based, starch-based, lipid-based, and cellulose-based stains, respectively, into smaller fragments, making them easier to remove during the washing process.
Bio-surfactants: Surfactants are essential components of washing powders as they help to remove dirt and oil from fabrics. Biotechnology allows for the development of bio-surfactants, which are surfactants derived from biological sources, such as bacteria or yeast. These bio-surfactants are more environmentally friendly than traditional surfactants as they are biodegradable and have lower ecological impact.
Microbial Strains: Biotechnology can be used to isolate, characterize, and optimize microbial strains that produce enzymes or bio-surfactants. Microorganisms, such as bacteria and fungi, can be engineered or selected for their ability to produce specific compounds that enhance the cleaning performance of washing powders.
Genetic Modification: Genetic modification techniques can be employed to enhance the properties of microorganisms used in the production of enzymes or bio-surfactants. This allows for the creation of microorganisms with improved characteristics, such as increased enzyme activity or enhanced stability under varying conditions.
Fermentation Processes: Biotechnology facilitates the use of fermentation processes to produce enzymes and bio-surfactants at a large scale. Fermentation involves the controlled growth of microorganisms in bioreactors, where they produce enzymes or bio-surfactants through metabolic processes. This enables the efficient and cost-effective production of these ingredients for use in washing powders.

If a researcher has a DNA sample with a concentration of 0.6 micrograms per microliter, how many microliters of DNA must be transfered to conduct a 50 microliter reaction if the final concentration should be 3.9 nanograms per microliter
Answer:
0.325 microliters
Explanation:
1 microgram = 1000 nanograms
DNA sample concentration= 1000 X 0.6 = 600 nanograms / microliters
We need a total of 50 microliter reactions, and the concentration should be 3.9 nanograms per microliter.
So, we need total 50 X 3.9 = 195 nanograms in 50 microliters.
Therefore, it required 195 / 600 = 0.325 microliters of DNA sample to be transferred.

Formation of new capillaries is a regulated process that occurs in a series of steps. Put the following steps of angiogenesis in the correct order.
A. Pinocytic vesicles fusing to form large vesicles
B. Endothelial cell extension of filopodia
C. Formation of capillary sprout
D. Stimulation of endothelial cell by VEGF
E. Creation of a lumen that runs through capillary sprout
Answer:
Explanation:
The correct order of the steps of angiogenesis is:
Stimulation of endothelial cells by VEGF
Endothelial cell extension of filopodia
Formation of capillary sprout
Pinocytic vesicles fusing to form large vesicles
Creation of a lumen that runs through capillary sprout
Angiogenesis is the process of creating new blood vessels from existing ones. It is a regulated process that occurs in response to various stimuli, such as tissue hypoxia or inflammation. The first step in angiogenesis is the stimulation of endothelial cells by vascular endothelial growth factor (VEGF). This protein promotes the proliferation and migration of endothelial cells, which are the cells that line the inner surface of blood vessels.
Next, the stimulated endothelial cells extend filopodia, which are thin, hair-like protrusions that help them to explore and migrate through the surrounding tissue. As the filopodia grow and interact with the extracellular matrix, they form a capillary sprout, which is a small, tubular structure that begins to take shape.
During this process, pinocytic vesicles, which are small, membrane-bound vesicles that are involved in the uptake of extracellular fluid and substances, fuse to form large vesicles. These vesicles help to provide the necessary nutrients and support for the developing capillary sprout.
Finally, the capillary sprout continues to grow and differentiate, eventually forming a lumen, or a central cavity, that runs through the center of the sprout. This allows blood to flow through the newly formed blood vessel.

How does scientists use information to make predictions in your own words and in a generalized manner?
Scientists create a broad principle or explanation to help anticipate future events using their understanding of past occurrences. The term "hypothesis" refers to the overall idea. Inductive reasoning is the category of reasoning that is involved (deriving a generalization from specific details).
How do scientist make predictions?A scientific prediction suggests the evidence that is in line with the hypothesis and can thus be used to the results of both current and previous experiments. As a result, even though these trials were carried out more than 200 years ago, we can make predictions about how they will turn out.
For the scientist, predictions serve as a point of reference. If predictions come true, the theory has been validated by the scientist. The hypothesis is disproved if the predictions are not confirmed. In either case, the scientist now has more understanding of the process being investigated.
Therefore, scientists create a broad principle or explanation to help anticipate future events using their understanding of past occurrences. The term "hypothesis" refers to the overall idea.
