gogolik [260]3 years ago
5 0

Answer:

Physical characteristics: Freshwater sponges are crustlike, branched, or clumped. The texture is fragile and soft, and the color is whitish or green. Freshwater sponges have irregularly scattered and barely visible water-exit holes.

Geographic range: Freshwater sponges live in North America, Europe, and Asia.

Habitat: Freshwater sponges live in standing and running fresh water.

Diet: Freshwater sponges are filter feeders.

Behavior and reproduction: Scientists know little about how freshwater sponges behave. These sponges reproduce asexually by forming buds in late summer that spend the winter in a dormant state and emerge from the adult in the spring. Freshwater sponges reproduce sexually during the summer, giving birth to live larvae.

Why would growing upright be a beneficial adaptation
Murljashka [212]

Answer:

1) Better access to food

2) Safety

3) Protection of vital organs

4) Recreation

5) Improved separation of tasks among organs (division of labor labor)

6) Increased potential energy

Explanation:

1) Better access to food

The upright growth of plants enable them to access the Sun's energy during photosynthesis for the production of glucose and oxygen without the need to move far for food

2) Safety

Growing upright help protect the food produced by the plant such as fruits from crawling animals and also protects the loosely attached leaves and fruits from the impact of kinetic energy of flood waters

3) Protection of vital organs

Having vital organs stored away from areas  that cause due to the energy of falling objects or the motion fluid along side particles that the fluid (wind or water) may carry such as debris is important for the survival of an organism. Vital organs are also protected from being trampled upon

4) Recreation

Growing uptight enables the seeds of the fruits of a tree to be dispersed to more distant locations such that the new offspring may find an improved growing environment

5) Improved separation of tasks among organs (division of labor labor)

Growing upright encourages compartmentalization, such that different parts of the plant perform specific functions to prolong the plant life

6) Increased potential energy

The energy output of an organism growing upright is more than one that is growing sideways which results in better survival probability.

gregori [183]

Answer:

Explanation:

A country with higher interest rates often has an increase in the value of that country's currency relative to nations offering lower interest rates.

If there is an interest rate increase in the United States but the interest rate do not change in Europe then the United States currency will increase in value relative to the currency in Europe.

Other Factors that affects the value of a country's currency aside increased interest are:

(1) Political stability

(2) Economic stability.

(3) The demand for a country's goods and services.

(4) country's balance of trade between imports and exports.

Aldosterone is a hormone secreted by the adrenal gland that activates the receptor protein to turn on genes that control water a
Leokris [45]

Answer:

The correct option is C

Explanation:

Since the receptor cells is mutated, the adrenal gland might (depending on the type of mutation) no longer be able to activate the receptor protein which will affect water and sodium flow in the kidney cells. Thus, <u>the flow of the downstream components (water and sodium) will be altered in the kidney which will ultimately affect the blood's volume.</u>
