Which clade of organisms is characterized as containing many extremophilic microbes?
А
archaea
B
eukaryotes
С
fungi
D
plants
Answer:
The answer is A.) Archaea.
The clade of organisms characterized as containing many extremophilic microbes is archea. The correct option is A.
What are archaea?A class of microbes known as archaea is related to yet evolutionary separate from bacteria. Numerous archaea have been discovered to survive in harsh conditions, such as high pressures, salt concentrations, or temperatures.
Extremophiles are the name given to these kinds of creatures. Single-celled microbes called archaea have a similar structure to bacteria. They make up the third domain of life and are unique from bacteria and eukaryotes in terms of evolution. Archaea are obligate anaerobes that exist in low-oxygen settings (e.g., water, soil).
Therefore, the correct option is A, archaea regarding the extremophile microbes.

Proteins made by free-floating ribosome's remain in that cell: whereas, proteins that travel through the endomembrane system leave by secretory vesicles.
Explanation:
A free-floating ribosome creates proteins within cells, but unlike normal ribosomes, this protein is left to float freely in the cell’s cytosol.
Furthermore, proteins that are synthesized in the rough endoplasmic reticulum will most likely be secreted into the extracellular environment.

This is done in the clinical trials to keep the whole process unbaised.
A gene carries the _________ for a trait.
Answer:
A gene carries the information for a trait.
Explanation:
Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.
A gene carries the information for a trait.
What is gene?The fundamental structural and operational component of heredity is a gene. DNA is the component of genes. Some genes serve as blueprints for the synthesis of proteins. Many genes do not, however, code for proteins.
A few hundred DNA bases to more than 2 million bases make up a gene in a human. Humans are thought to have between 20,000 and 25,000 genes, according to the Human Genome Project, an international research project that aimed to decipher the human genome's sequence and catalog its genes.
Every gene is present in two copies, one from each parent, in every individual. The majority of a person's genes are the same in all persons, but a tiny fraction (less than 1% of the total) are slightly different.
Therefore, A gene carries the information for a trait.

O C. mitochondria 2. Where is the major site of photosynthesis in a plant? * O A. the stem O B. the roots O C. the leaves
Answer:
Option C
Explanation:
The answer to this question is option C or "the leaves." The major site of photosynthesis in a plant is where the chloroplasts are located because it contains chlorophyll which is where photosynthesis takes place, chloroplasts is in all the green parts of a plant stem, leaves, and even the branches but it takes place mainly in the leaves of a plant because there is more leaves then roots or branches.

What cell parts are common to What cell parts are found only in plant cells? What are found only in animal cells?
all of these cells?
Answer:
The organelles found only in plant cells include- chloroplast, cell wall, plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis. What is the composition of a plant cell wall? The cell wall of a plant is made up of cellulose
Animal cells are eukaryotic cells or cells with a membrane-bound nucleus. Unlike prokaryotic cells, DNA in animal cells is housed within the nucleus. In addition to having a nucleus, animal cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation
Answer: the plant cell has a cell wall, chloroplasts, plastids, and central vacuole structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.

volcanic eruptions can affect climate by
Answer:
The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.
Hope this helped, have a good day
Answer:
Volcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. Injected ash falls rapidly from the stratosphere -- most of it is removed within several days to weeks -- and has little impact on climate change

What other factors did you modify for BEE? Why do you think you need to consider these factors with caloric intake?
Answer:
The activity factor was modified. Ambulating indicates that the person is active. Even small activities require energy. So, people who can walk around and aren’t bedridden expend more calories than people who need to be on bedrest all day. Also, when the stress factor was changed to severe infection, the caloric requirement increased. This increase is probably because the immune system requires more energy to fight off the infection

Do all living things obtain the matter and energy they need to live and grow in the same way?
Answer:
Explanation:
This means all living organisms must obtain and use energy to live. Energy is the power to do things. ... A living organism can either make its food or depend on others to make food for them. For example, green plants produce their food from a process called photosynthesis.
Living things obtain energy and food to grow but different organisms do in different ways plants depend on the sun for photosynthesis.
How do living things obtain energy?Every living thing has a unique method of getting nutrients. Protozoans and other animals are among the creatures that obtain nutrition by eating food. Through the process of photosynthesis, plants and algae produce their own sustenance.
Animals consume food and drink to get the substance and energy they require for their biological activities.
A producer is an organism that produces its own nourishment. Sugars, a source of both energy and substance, are produced by plants using the energy from sunshine.
Therefore Plants are one type of creature that can produce its own food, to obtain energy.

Hi there!
Photosynthesis involves carbon dioxide (CO2) and water (H2O) as the reactants with glucose (C6H12O6) and oxygen (O2) as the products. We can write a basic chemical equation:
[tex]CO_{2} + H_{2} O - (light) -> C_{6} H_{12} O_{6} + O_{2}[/tex]
The equation has to be balanced, so the final equation for photosynthesis would be:
[tex]6CO_{2} + 6H_{2} O - (light) -> C_{6} H_{12} O_{6} + 6O_{2}[/tex]
The chemicals in correct order are:
[tex]CO_{2}\\H_{2}O\\ C_{6}H_{12}O_{6}\\ O_{2}[/tex]
Describe how positive control in prokaryotes can be altered by the external environment
Answer:
The positive control is control when there is an activator present which acts as a regulatory protein so the operon and activator binds and initiates the stimulation of transcription to express the gene. In absence of this activator or regulatory protein, the operon will be inactivated.
External environmental stimuli can lead to alteration of the positive control in prokaryotes such as excess lactose in the environment. These environmental stimuli can induce transcription in prokaryotes.
In this example, if glucose is not available in the environment, the transcription of the lac operon will be induced by the presence of lactose in the environment.
A group of students wanted to know if millipedes prefer moist or dry environments. They suspected that millipedes would prefer moist environments because they had observed that millipedes are usually found under decaying logs.
Answer:
The suspicion of the students are very correct. Millipedes prefer damp environments. They need water moisture to survive.
Explanation:
Millipedes are known as arthropods. An Arthropod is an animal without a spinal vertebra, which possesses a segmented body, paired jointed appendages, and an exoskeleton.
They are found to be very ardent and quicker at recycling natural waste than animals and plants.
Without adequate moisture, Millipedes can die within 48 hours.
