The effect of species loss on the environment is researched by an ecologist in an ecosystem. Thus option C is correct.
An ecosystem is defined as the structural and functional unit of where the living organisms interact with each other and their surrounding and was coined by A.G.Tansley, an English botanist, in 1935.
The basic components of an ecosystem are Biotic Components and Abiotic Components, both the components are interrelated with each other by doing energy flow.
Biotic components belongs to all living components like autotrophs, heterotrophs and saprotrophs. Autotrophs or producers like plants.
Second is consumer or heterotrophs which depend on other organisms for their food, can be primary consumers, secondary consumers and tertiary consumers.
Primary consumers are herbivores, Secondary consumers can be either carnivores or omnivores. Tertiary consumers get energy from on secondary consumers.
Quaternary consumers are carnivores and Decomposers include saprophytes feed on dead and decaying matter.
Thus option C is correct.

(4) They are released by the parathyroid glands.
a. 1 only
b. 1 and 2
c. 1, 2, and 3
d. 1, 2, 3, and 4
B) ultrasound imaging
C) amniocentesis
D) blood transfusion
E) X-ray
The obstetrician would most reasonably offer procedure CVS (Chorionic Villus Sampling) to her patient. Therefore option A is correct.
CVS is a prenatal test performed between 10 to 13 weeks of pregnancy. It involves taking a small sample of cells from the placenta to analyze the fetal DNA for genetic disorders.
This procedure allows early detection of serious disorders, providing valuable information to the parents about the health of their fetus. Ultrasound imaging can provide structural information about the fetus but may not detect biochemical disorders.
Amniocentesis is typically performed later in pregnancy and is used for different purposes. Blood transfusion and E) X-ray are not relevant to detecting fetal disorders.
Therefore option A is correct.

Answer:
The dolphins population may diminish a little.
Explanation:
Crabs are one of the many things dolphins eat, and, as the prompt suggest, they cannot live in temperature greater than 60 degrees F. If climate change makes the temperature 62 degrees F, the crab population will all die. However, note that dolphins do not only eat crabs, as they have other food sources. However, crabs are a major population, so we can see a disruption in the food web, with there being less dolphins than usual.

a) passive stretch, contracted, relaxed
b)passive stretch, relaxed, contracted
c) none of the above
Certain bacteria living in the roots of plants convert nitrogen to a form plants can use, and animals obtain their nitrogen by eating those plants.
Certain bacteria convert nitrogen to a form animals can use, and animals obtain their nitrogen by inhaling this nitrogen.
Answer: Option B
Explanation:
The best part of the nitrogen cycle is that it assures that nitrogen is made available to the plants and animals present in the environment.
There are certain nitrogen fixing bacteria present in the soil (roots of the plant) that converts the nitrogen into the form by which it can be utilized by the plants.
This nitrogen present in the plants is consumed by the animals and this is how the animals obtain nitrogen.
