2. Most male crickets produce a mating song by rubbing together their curved
wings. In a certain geographic area, parasitic flies detected male crickets singing
and deposited their larvae into them, which killed the crickets. Eighteen
generations later, the number of males with flat wings has increased to 90%. The
flat-winged crickets do not sing, but are still able to mate with females, and
parasitic flies cannot detect them. Which type of selection is occurring in this
cricket population?
O
Artificial
O
Directional
O
Disruptive
O
Stabilizing

Answers

Answer 1
Directional selection, as one phenotype is greatly favored over another

The stomach level of organisation is organ, because it is made up of group of cells and tissues to form part of the digestive system.

Heart muscles is made up of organs as it is the combination of tissues and cells therefore a muscular organ,

DNA -represents a molecular level,but because it is located in the cells , its represented this level.

Homeostasis can require the control of many different variables in organisms. Homeostasis regarding internal body temperature is very important for many organisms. How is this different among ectotherms and endotherms?

Answers

Answer:

The term homeostasis refers to balance, where an organism seeks to maintain the balance of the temperature of its organism in order to persist in life.

There are organisms that are considered ectotherms, with which they release heat to the external environment in order to balance said increase in temperature and not denature their own proteins (such as enzymes, structural proteins, receptors, second messengers, etc.). On the other hand, in the case of endotherms, take energy from the medium to increase your body temperature and maintain it, since otherwise you could enter hypothermia.

In the human organism these principles occur both, not simultaneously, but according to the external temperature in which the human is, ectothermic / catabolic processes in heat stages and endothermic or anabolic processes in the cold stage.

Explanation:

In simple words, endotherm is the heat taken from the medium and exotherm or ectotherm is the release of heat to the medium.

This is so simple in objects, but in living organisms these processes have a reason, and that is why we explained above, when looking for a constant temperature these processes are responsible for mediating balance.

Good and conducive environment should be provided for the animals.

Routine cleaning to avoid outback of diseases

Adequate resources should be provided this include food to avoid eviction of important species.

Geosphere is made up of the crust they form the layer of soil that support growth of plant and also supply nutrients.

Atmosphere is made of gas some of which help sustain life. Example is oxygen, carbon dioxide

Hydrosphere form the liquid portion of the earth it included large water bodies that serves as habitat for aquatic organism.

Oxygen and carbon are been released into the atmosphere where they are been taking up by plant or animal dead and remains of this organism lead to the release of this gases in both organic and in organic form back into the soil where it is taken up by plants back into the atmosphere and some are washed in the water bodies.

Plants takes in carbon-dioxide from atmosphere, absorbs nutrients from the soil through their root and water from the water table needed fro their growth.

Describe the organisms reproductive strategy:



discuss how this strategy is an adaptation for this organism:

Answers

Answer:

I will go with sponges :)

Sponges reproduce asexually. The parent begins budding, when the buds grow to a certain point, they break off and drift with the oceans current to a new place, settle down into the sand or rocks, and start the cycle all over again. Since sponges are stationary organisms (meaning that they cannot travel on their own.) They rely on the oceans current to spread their species across the oceans.

Answer:

I would do a Moon Jellyfish

Explanation:

Moon jellyfish reproduce during two different stages in their life cycle. During the medusa stage, they reproduce sexually by releasing sperm and eggs into the water. The method of reproduction used by jellyfish polyps is known as budding, and it does look like a plant growing a new bud for a flower. The polyp essentially clones itself. The clone buds out of the original polyp and detaches to float freely in the water.
