Answer:
The main difference is that in prokaryotic cells the genetic material is not separated from the cytoplasm and eukaryotes present the genetic material is organized in chromosomes surrounded by a membrane that separates them from the cytoplasm.
Explanation:
All living beings are made up of cells that, depending on their structure, can be eukaryotic or prokaryotic. The eukaryotic cell is the building block of life for protozoa, fungi, plants, and animals. It is characterized by keeping its genetic material packed within a membrane, forming the nucleus. It also has other intracellular structures surrounded by membranes, known as organelles: mitochondria, vesicles, chloroplasts, among others.The prokaryotic cell is a simple organism composed of a membrane and cytoplasm, which lacks a nucleus and does not present organelles like eukaryotic cells ( mitochondria, chloroplasts and endoplasmic reticulum). In addition, it has a cell wall that supports the cell.
Describe three other features of a bacterial cell.
Answer:
hope it helped
Explanation:
Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.
The features of a bacterial cell are the following:
Bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.
They are essential in the decomposition processes of organic matter, necessary for the recycling of elements such as carbon or nitrogen.
They reproduce quickly and by asexual procedures, which consist of the replication of the progenitor cell in two exactly equal to it (binary fission).They are made up of a single cell without a cell nucleus, but with a nucleoid (an irregular region where the circular DNA of prokaryotes is found).They have a peptidoglycan cell wall that covers the cell outside the plasma membrane.Scattered throughout the bacterial cytoplasm are ribosomes (in which protein synthesis takes place) and there are also often plasmids (small non-chromosomal DNA molecules).Some bacterial cell also have capsules, a rigid protective structure that is outside the cell wall and flagella to move (if they are mobile).Therefore, we can conclude that bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.

What is one trait that could be used to separate these albatrosses into two groups of two birds each?
The correct answer to this open question is the following.
You did not attach the options for this question. However, we can answer the following.
Although there are no pictures of the Albatross, we can say that one trait that could be used to separate these albatrosses into two groups of two birds each is "a large group of solid black feathers vs. black and grey patterned feathers."
If someone ask you what are the birds with larger wings, you probably would answer "the Bald Eagle," Or any other kind of eagle. Maybe the Southamerican Condor. And those answers are incorrect. The correct answer: the Albatross.
This is a carnivore bird which wingspan varies from 6.5 to 11 to 11 feet, Its average weight is 22 pounds. These impressive birds can use their long wings to fly over the seas for miles and miles, without taking a rest.

A landslide on a mountain
Uplift of mountain ranges
Breakdown of rock into sediments
Formation of a canyon
The changes to Earth's surface is most likely to represent space and time on the smallest scale is a landslide on a mountain.Thus, option A is correct.
What is the procedure of formation of Clastic sedimentary rocks?
Clastic sedimentary rocks are formed by the weathering process, In this process rocks get breakdown into sand, clay particles by the wind, water, and ice.
Clastic sedimentary rocks are also known as sandstone, and they are made of rocks and minerals. They are classified based upon composition, size, and texture.
Breccia is a clastic sedimentary rock with angular particles. Breccia is composed of particles that have diameter of greater than two millimeters. Breccia is formed by accumulation of angular broken rock or mineral debris. Breccia differ in composition according to the composition of mineral and rock from which the angular fragments were formed.

The diagram shows a planet orbiting the Sun. Fill in each box with the statement that best describes each part of the diagram.
direction of gravitational
pull of the Sun on the planet
the planet’s resultant
orbital path
direction of the planet's
velocity and momentum
Answer:
direction of gravitational pull of the Sun on the planet
Explanation:
A planet orbiting or revolving around the sun due to gravitational force of the Sun on the planet which attracts the planet and compel the planets to move in a circular path. If this force of gravity is not applied on the planets, the planets will move in a straight line instead of circular direction so gravitational pull of the Sun on the planet is very necessary for moving planets in a circular path.

What is a hormone?Hormones are a class of signaling molecules found in multicellular organisms. These molecules are sent to distant organs by complex biological processes in order to regulate physiology and behavior. Hormones are also known as endocrine signaling molecules. Hormones are essential for the proper development of all organisms, including fungi, plants, and animals.
There are three primary categories of hormones: those derived from lipids, those derived from amino acids, and those derived from peptides.
