A student will measure and record the growth (in height) of two flowering plants every other day for 20 days. Each plant will receive 200mL of water each day, but only one plant will receive 10mL of fertilizer. whats the independent variable, dependant variable, and the standardized variable?

Answers

Answer 1

Answer:

The correct answer is -

the independent variable - if fertilizer added or not,

the dependant variable - the height of the plant and

the standardized variable - 200ml water

Explanation:

In this study, the student wanted to see the effect of the fertilizer on the growth of the plant so the independent variable is the treatment of the fertilizer as manipulated or the independent variable is the factor which is affected or changed purposely during an experiment while other variables remain constant.

The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.

The standardized or the control variable is the variable that remains constant throughout the experiment, 200 ml water treatment is the control variable in this experiment.

Which clade of organisms is characterized as containing many extremophilic microbes?
А
archaea
B
eukaryotes
С
fungi
D
plants

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.

If bugs did disperse what are the costs and benefits of accepting a host plant of either species?

Answers

Answer:

How could a dispersing bug know what species of plants it would be settling on? A bug can know what bug it is landing on by sight, smell and taste. All insects disperse, even those without wings, so the question contains a false assumption and is therefore unanswerable. In general, the contribution of any particular trait to an organism's fitness depends on the details of the life cycle. Without knowing those details, it's impossible to say.

For Bugs, I will say at no cost at a because the bug cannot know the the harm or negative impact a host plant can do to it.

But for benefits, there are a lot of benefits of accepting a host plant. Some of the benefits are:

It is an avenue or a strategy for egg laying females when larvae must feed on plant so as to complete development

bugs or insects are attracted to flowers due to its scent or brightly coloured petals. These flowers produce a sweet liquid, called nectar, which the bugs or insects feed on.

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.

C. ATP. .
D. water molecules.

Answers

Answer:

A. light.

Explanation:

Photosynthesis is the process whereby green plants manufacture their food in form of sugars (glucose) in the presence of sunlight as energy source. The process combines carbon dioxide and water to produce glucose and oxygen, with light source from the sun providing the required energy.

High energy is stored in the bonds of the glucose molecule produced (C6H12O6). This energy emanates from the SUN (solar energy), which the photosynthetic process cannot so without.
