A gene carries the _________ for a trait.

Answers

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.

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.

Answers

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.

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.

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

Answers

Okay here you go. The cons to climate change would be anything negative. Soooo
1. Trauma from floods
2. Droughts
3. Heat Waves
4. More heat = longer allergy seasons and more respiratory diseases.

The pros to climate change would include anything positive. Soooo
1. Fewer winter deaths
2. Low energy costs
3. Better agricultural yields
4. Fewer droughts.

Here is your conclusion.
Climate change may have a couple of pros but overall it’s terrible and we don’t want it to happen. It’s dangerous and could end the world. We need to take care of our earth and it’s as simple as not littering. Climate change is bad and just about every living thing would go extinct. Aka animals and humans.

A
Water, Plants, and Birds
B
Birds and Plants
С
Soil, Plants, and Birds
D
Water, Sunlight, Soil, and Air

Answers

Answer:

Water, Sunlight, Soil, and Air

Explanation:

Abiotic factors are the non-living components of an ecosystem. These are physical factors, such as water, sunlight, soil, and air.

In contrast, biotic factors are the living components and include birds and plants.

The way the biotic and abiotic factors interact with one another forms the ecosystem. The biotic factors rely on the abiotic factors to sustain their life.

A scientist is using a species of green algae to study the electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibit PS I but do not affect PS II (case 2).
Which of the following results is expected?
A)in case 1, only PS I completely loses function; in case 2, no proton gradient is produced.
B)In case 1, only PS I completely loses function; in case 2, a proton gradient is still produced.
C)In case 1, both PS I and PS II completely lose function; in case 2, no proton gradient is produced.
D)In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.

Answers

Answer:

D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.

Explanation:

The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.

The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.

In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.
