Answer:

1. Empty calorie food

2. Nutrient dense food

Explanation:

The modern research has helped humans classify the food on the basis of the calorie content present in them and the nutrient content.

Some food substances are nutrient-dense food which contains a high amount of calorie per serve and provides high nutrient content per serving whereas some food products which do not supply enough nutrients per serve.

Thus, Empty calorie food and Nutrient dense food are correct.

Cells need to bring in molecules to carry out cellular processes. Often, this requires moving the molecules across the cell memb
aniked [119]

Answer:

B (active transport using ATP)

Explanation:

Movement of substances normally occur in the direction of concentration gradient/difference i.e. the difference in concentration of a substance across a membrane. Letting molecules diffuse or pass down their concentration gradient does not require energy but pumping those molecules against gradient requires energy in form of Adenosine triphosphate (ATP). This process is called Active transport.

In order to perform certain cellular processes, cells need to move substances from their surroundings into the cell across their cell membrane. Moving this substances against the concentration gradient between the cell membrane and its extracellular fluid requires energy (ATP).

An example is the sodium-pottasium pump employed by animal cells in which they expend energy to move K+ molecules into the cell and Na+ molecules outside the cell against the concentration gradient of their cell membrane and extracellular solution.

18) The Susquehanna River, which runs through the states of New York, Pennsylvania, and Maryland,
kirill [66]

The biodiversity will decrease due to an increase in pollution is the effect will have on the biodiversity on the river ecosystem.

Option A

<u>Explanation:</u>

Biodiversity is the actual collection of total amounts of flora and fauna present in a particular ecosystem. The river ecosystem consists of the aquatic plants, the aquatic animals like fishes,etc and even the surrounding land plants and animals, who utilize the river water for their living.

The inclusion of the polluted sewage of the surrounding area into the river directly mixes several chemicals to the water, which are potentially harmful for all the animals living there. This leads to destruction of the flora and fauna of both water and lands surrounding them. This hampers the biodiversity of the water as well as surrounding land.

Explain why meiosis cannot happen without mitosis.
Oksi-84 [34.3K]
The mechanism is straightforward: in Metaphase one of Meiosis, chromosomes line up in two lines, with homologous across from each other, which allows them to interact by crossing over. In Metaphase of Mitosis, the chromosomes are all lined up single file, so the homologous chromosomes cannot interact.

A great deal of the Blue Ridge was eroded. The eroded rock eventually finally settled in Virginia’s coastal plain. What process
Lisa [10]
The process is called Erosion. During the Erosion, materials from one place such as soil and rocks will be transport to another location. The process is also contrast to the process called deposition which responsible for the control of the arrival of the materials to a new place like the rocks from Blue ridge Mountain to Virginia's Coast.
