Algae → larva of a prawn → anchovy → eel. In this food chain, algae obtains about 4,000 KJ of energy from the sun. What is the a

mount of energy that will be available to the eel and why?

The energy passed to each subsequent trophic level in food chain is 10% of the energy in the last trophic level. Therefore:
Algae- 4,000 kJ
Larva- 400 kJ
Anchovy- 40 kJ
Eel- 4 kJ

The reduction in the energy passed is due to the fact that when an organism consumes a given amount of energy, it is utilized for different functions within the organism's body and is lost in a form that can not be recovered, for example, as heat energy.

A scientist discovers a new species near coral reefs in Australia. She finds that this single-celled species is photosynthetic (
pochemuha

Answer:

1. Eukaryotic

2. Eukaryota

Explanation:

1. Eukaryotic- The newly found species has a cell wall and contains membrane-bound organelles. The presence of membrane-bound organelles shows that the cell is a Eukaryotic cell.

2. Eukaryota- the species is single-celled with the presence of cell wall without peptidoglycan. This shows that the species could belong to the Eukaryota domain proposed by Carl Woese.

Thus, 1. Eukaryotic and 2. Eukaryota is the correct answer.

Which of the following accurately lists the taxonomic groups in order from broad to specific? A. Kingdom, phylum, class, order
Pavlova-9 [17]
<h2>Answer</h2><h3>A. Kingdom, phylum, class, order</h3><h2>Explanation:</h2>

The taxonomic groups are basically used in the scientific classification from most general to most specific. There are seven main taxonomic levels such as kingdom, phylum or division, class, order, family, genus, species. The most specific classification is genus and species. The broadest classifications are by domain and kingdom.

Jackson, a 4-year-old boy, is unable to get the measles (MMR) vaccine due to a severe allergy to the antibiotic neomycin. Jackso
lilavasa [31]

Answer:

In Lincoln Elementary School.

Explanation:

I advise them to send Jackson to Lincoln Elementary School which has 95% vaccination rate for MMR because there is less chances of having measles to Jackson as compared to Oak Crest Elementary School having 80% vaccination rate for MMR. Yes, Jackson is at risk of contracting measles because of no immunity acquire against measles disease by its body. The vaccine can provides immunity to Jackson from the disease but he can't take it due to allergy.

Scientists studied reproduction in the New Zealand mud snail. They wanted to determine whether reproducing sexually or asexually
lubasha [3.4K]

A hypothesis is a claim that expresses a relationship between variables. D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

<h3>What is a hypothesis?</h3>

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact. It is a claim of how it works a relationship between two or more variables.

The researcher hypothesizes in order to predict what is going on or what is expected to occur.

A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relationship between the involved variables. It must be objective. Usually, it is written in the present time.

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.  

In the exposed example, researchers wanted to determine whether reproducing sexually or asexually was more beneficial for the snails.

Options,

A) <em>Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation. </em>

The benefit of reproducing sexually is that the risk of mutation is lower.

B) <em>Asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring.</em>

<em />

The benefit of reproducing asexually is that a higher number of descendants are produced, which increases reproductive success.

C) Sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation.

The benefit of reproducing sexually is that it increases genetic variation.

D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

The benefit of reproducing asexually is that there is no need for social interaction.

Social interaction does not really benefit snails as a species. This is not a variable that might influence in a significant way snails.

However, variables like the mutation rate, variability, and the number of descendants are useful to test how they benefit or not the snails.  

The hypotheses that would least likely aid the scientists to answer the question is <u>option D</u>.
