If a hawk eats 30% of the weasel population, weasels eat 30% of the mouse population, and
mice eat 20% of the wheat plants, calculate the total numbers of each organism that exist in
this ecosystem
a. Start by finding how many weasels there are to support the one hawk
i. # of weasels eaten 7.3 = total weasels
ii. total weasels x # of mice needed / .3 = total mice
iii. total mice x # of wheat plants needed / .2 = total wheat plants
Answers
Answer:
a. Approximately 1,003 weasels, 3,345 mice and 16,729 wheat plants per one hawk are in the ecosystem
Explanation:
The percentage of the weasel population eaten by a hawk = 30%
The percentage of the mouse population eaten by a weasel = 30%
The percentage of the wheat plants population eaten by a mice = 20%
a. One hawk needs 330 kJ of energy per day, which gives 330 kJ × 365 = 120,450 kJ per year
Let 'x' represent the number of weasels to support one hawk, we have;
0.3 × x = 120,450 kJ/year/(400 kJ) = 301.125
x = 301.125/0.3 = 1,003.75
The number of weasels required to support one hawk per year ≈ 1,003 weasels
The total weasels ≈ 1,003
ii) The number of mice needed, y = x/0.3 = 1,003.75/0.3 = 3,345.8[tex]\overline 3[/tex]
The total mice, y ≈ 3,345 mice
iii) The number of wheat flower needed, z = y/0.2
∴ The number of wheat flower needed, z = 3,345.8[tex]\overline 3[/tex]/0.2 ≈ 16,729.1[tex]\overline 6[/tex]
The total wheat plants ≈ 16,729.

A guard bees job is to protect the hive from intruders, a job that can lead the guard bee to sacrifice its own life. If the guard bee cannot reproduce, how do genes for altruism increase in the population
Answers
Answer:
Altruism genes are dominant, so they can be inherited more easily. Bee colonies are so large that the loss of a few individuals will not affect the gene pool.
Explanation:
The altruistic genes are easily and sophistically inherited from the parents to their offspring. These genes are dominant that increase the size of the population by sacrificing their own life for the benefit to pass their genes to the next generation.
What do you mean by Altruism?Altruism may be defined as a behavior in which one individual sacrifices their own fitness value to increase the fitness value of the other individual that is genetically as well as closely related.
Altruistic behavior is often associated with Kin selection. The genes for altruism are exposed to the population directly from the parents and then passes to the offspring.
Therefore, it is well described above.

Explanation:

hope this make sense:)
Macromolecules like proteins and nucleic acid are large structures that are essential for biochemical processes. The figure shows the structure of DNA.
What is DNA?DNA is deoxyribonucleic acid that is a nucleic acid and is an important genetic material found in living organisms. It is composed of a double helix structure.
The nucleotide structure of the DNA constitutes deoxy sugar, phosphate groups, and nitrogenous bases like adenine, thymine, guanine, and cytosine.
It cannot be RNA as in RNA, uracil is present at the place of thymine. It cannot be an amino acid or protein as well because they are not composed of the amine, carboxylic, and the R group.
Therefore, the given figure is option A. DNA molecule.

Answers
Answer:
Debido a la presencia de partículas pesadas.
Explicación:
Debido a la presencia de carga positiva en el núcleo del átomo de Thomson, las partículas alfa α rebotaron cuando chocaron con el protón porque el protón es una partícula pesada y la presencia de neutrón la hace más pesada. Debido a la presencia de partículas pesadas en el núcleo, las partículas alfa no pueden atravesarlo. Solo puede pasar a través del átomo de Thomson donde hay un espacio vacío en el átomo.

For those individuals who have an allergic reaction to cats, a company in Los Angeles promises relief. They offer a new line of cats genetically modified to eliminate or reduce their allergy-causing properties. The development of this new line of cats most likely involved A. using natural selection to produce a new variety of cat B. altering the reproductive rate of cats C. changing the behavior of cats D. manipulating the DNA of cats
Answers
Answer: D. manipulating the DNA of cats.
Explanation:
Deoxyribonucleic acid (DNA) refers to the organic chemical which consists of genetic information. The DNA can be found in the cells of organisms.
Since the new line of cats are genetically modified to eliminate or reduce their allergy-causing properties, then we can infer that the DNA of the cats have been manipulated. In this case, the allergy causing property won't be passed across to the offspring since the DNA has been manipulated.

Explanation:
Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals. The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; kingdom, domain, phylum, family, order, class, species and genus.
Generally, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.
A chordate can be defined as an animal found in phylum chordata of the animal kingdom such as vertebrates, cephalochordates, tunicates, etc.
The four (4) shared anatomical features or characteristics of chordates includes the following;
I. Notochord.
II. Dorsal hollow nerve cord.
III. Pharyngeal slits.
IV. Post-an_al tail.
In this scenario, you find a small, elongated animal that has segmental musculature, a coelom, and a complete digestive tract. Thus, this animal is a chordate.
