Answer:

Genetic drift

Explanation:

Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time. These variations in the presence of alleles are measured as changes in allele frequencies.

Appears to contain a multilobed nucleus. what is the most likely identity of the observed leukocyte?
Brrunno [24]

Neutrophil is the most likely identity of the observed leukocyte

<h3>What is Neutrophil ?</h3>

The most common type of granulocyte in humans are neutrophils, also known as neutrocytes or heterophils, which make up between 40% and 70% of all white blood cells. They are an essential part of the innate immune system, and they have different functions depending on the species.

The bone marrow-produced stem cells are differentiated into the neutrophil-killer and neutrophil-cager subpopulations. Due to their potential ability to access tissues that other cells or substances cannot, they have a limited lifespan and are very migratory. There are two different types of neutrophils: banded and segmented neutrophils (or bands). They belong to the same family of cells as basophils and eosinophils, which is known as PMNs.

I need help with a dang Mono Lake ecosystem thingy
jeyben [28]

Nestled at the edge of the arid Great Basin and the snowy Sierra Nevada mountains in California, Mono Lake is an ancient saline lake that covers over 70 square miles and supports a unique and productive ecosystem. The lake has no fish; instead it is home to trillions of brine shrimp and alkali flies. Freshwater streams feed Mono Lake, supporting lush riparian forests of cottonwood and willow along their banks. Along the lakeshore, scenic limestone formations known as tufa towers rise from the water's surface. Millions of migratory birds visit the lake each year.

From 1941 until 1990, the Los Angeles Department of Water and Power (DWP) diverted excessive amounts of water from Mono Basin streams. Mono Lake dropped 45 vertical feet, lost half its volume, and doubled in salinity.

The Mono Lake Committee, founded in 1978, led the fight to save the lake with cooperative solutions. We continue our protection, restoration, and education efforts today with the support of 16,000 members --and we host this Website.

In 1994, after over a decade of litigation, the California State Water Resources Control Board ordered DWP to allow Mono Lake to rise to a healthy level of 6,392 feet above sea level--twenty feet above its historic low. It is rising toward that goal -- click here for the current lake level, or visit one of the other links on this page for more of the Mono Lake story.

“The study of cell biology is directly
Marat540 [252]

Answer:

I agree.

Explanation:

Cell biology and technology are so connected that there is even a science called biotechnology, which is the literal union of these two strands.

Biotechnology is an area that aims to develop biological products and processes with the help of science and technology. The United Nations (UN) classifies biotechnology as "any technological application that uses biological systems, living organisms, or derived beings, to manufacture or modify products or processes for specific uses".

Biotechnology covers different areas of knowledge that include basic science (such as molecular biology, microbiology, etc.), applied science (such as immunological, chemical and biological techniques) with different technologies (such as information technology, robotics and process control).
