How does the rate of extinction compare to the rate of species formation on earth today?

A depression in the ground due to a cave collapse or acidic water dissolution of limestone is called a

SpyIntel [72]

This would be called a D. Sinkhole. Sinkholes occur because groundwater washes and deteriorates at limestone under the surface. This leads to underground gaps. Once the pressure becomes high enough, the sinkhole collapse from gravity leaving a dent similar to potholes in the road.

What does an ecopsychologist study? a. the mental health of environmental scientists b. the relationship between animals' intera

Butoxors [25]

Answer:

The correct answer is d. the relationship between a person's mental health and the environment.

Explanation:

Ecopsychology is aimed at identifying the way in which the emotional aspects of human beings are influenced by the environment, that is, ecopsychology collects multiple experiences that connect human development with environmental awareness. Ecopsychologists are oriented to the search for the well-being of the human being through its connection with natural processes through the understanding of the complex interrelationships between people and the environment.

Trypanosome infections evade attacks by host immune systems through which of the following mechanisms? A. insertion of its DNA i

lapo4ka [179]

Answer:

<h2>Through production of news cell-surface proteins with a different molecular structure by each new generation. Letter B</h2>

Explanation:

The life cycle of theses paratises extracellular alternate between the salivary glands of the insect transmitter and the blood of the mammal. During the set prior to the entry into the host, the metacylic parasites express a dense over formed by the Variant Surface of Glycoprotein, after entering to the mammal host they transform into a morphology that stays in the bloodstream.

The parasites have to manipulate hosts cells in order to avoid the production of antimicrobial molecules and to benefit from growth factor production.

Intracellular protozoa have a remarkable adaptive capacity as they are able to resist killing by remodelling the phagosomal compartments where they reside and by interfering with the signalling pathway that leads to cellular activation.

Answer: Oxygen

Explanation:I hope it helps . i have breifly explained it .

Oxygen gas is one of the products of photosynthesis.

Which reactant is the source for oxygen gas and how is it released?

A .

Water, released when sunlight splits it into oxygen and hydrogen ions

B .

Glucose, released when glucose is broken down into carbon dioxide gas, oxygen gas and water

C .

Carbon dioxide, released when sunlight splits it into carbon and oxygen gas

D .

Electrons, released when they strike the chloroplasts

Green plants capture energy and convert it into chemical energy by the process known as photosynthesis. During photosynthesis, carbon dioxide and water are transformed into simple carbohydrates and oxygen is liberated into the atmosphere.

light

6CO2 + 12H2O ----------------> C6H12O6 + 6O2

chlorophyll

Water is also used as a source of hydrogen required for reduction of carbon dioxide to form carbohydrate.

Water is oxidised in presence of light and chlorophyll. Hydrogen is removed from water and oxygen is released as follows:

light

4‎H20 ---------------> 2‎H20 + 4H+ + 4e− + O2

chlorophyll

or,

2‎H2O ----------------> 4H+ + 4e− + O2

Hence the source for oxygen gas is water and it is released when water splits in the presence of sunlight into oxygen and hydrogen ions.

So, the correct answer is 'Water, released when sunlight splits it into oxygen and hydrogen ions'.
