1) Eubacteria cells lack a nucleus, and are therefore________
Viewing eubacteria requires a microscope,because they all single celled organisms.another word for single celled is_______
Answer:
The correct answer is - prokaryotic and unicellular.
Explanation:
Eubacteria is known as the true bacteria and belongs to the prokaryotic type of cells which is characterized by no double-membrane organelles or the nucleus. All the genetic material is present in the cytoplasm itself.
These bacteria are single-cell microscopic organisms as they are very minute to see by the naked eyes and required a microscope to study. Another word for the single-cell organisms is unicellular.

Does natural selection affect humans? How and why
Answer:
Yes it does affect humans.
Explanation:
Natural selection acts on the phenotype, but evolution is a change in the frequency of alleles in a population over time, a change in genotype. So natural selection acts on phenotype, but it is the connection to genotype that makes it the mechanism of evolution. Many traits vary among different members of a population of humans and animals, from body size to hair color, and those differences are often linked to differences in genes. Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. In scientific terms, these hazards are referred to as selection pressures. They put pressure on us to adapt in order to survive the environment we are in and reproduce. It is selection pressure that drives natural selection "survival of the fittest" and it is how we evolved into the species we are today.
Choose a statement that explains why competitive exclusion occurs between different species.
Limited resources are easily shared.
There are unlimited resources in the ecosystem.
Competition decreases the health of all animals.
One competitor is best at using a limited resource.
The statement "Limited resources are easily shared" is the one correct about the competitive exclusion between different species.
What is competitive exclusion?It is the result of the competition in which a species is expelled by another more efficient species from a part of the available habitat.
Characteristics of the competitive exclusionThe competitive exclusion principle states that two species cannot occupy the same ecological niche in the same habitat.If there are limited resources, eventually one species will exclude the other, given a certain period of time, through “competitive exclusion”.Therefore, we can conclude that the competitive exclusion states that two species occupying the same niche cannot coexist in the long term since they would enter into competition for limited resources.

Which product is the result of light reactions in photosynthesis? O A. Water B. Glucose O c. Carbon dioxide OD. Oxygen
Answer:
D. Oxygen
Explanation:
Plants absorb carbon dioxide (CO2) and release oxygen for humans and animals to breathe in. Afterward, they'll release CO2 for plants to absorb, which forms a cycle.
Answer:
Oxygen
Explanation:
Both light dependent and light independent reactions in photosynthesis create glucose. But, only light dependent reactions convert carbon dioxide to oxygen.
Light independent: Carbon dioxide + water --> ATP and NADP(Energy/Glucose) and water
Light dependent: Carbon dioxide + water + light --> Glucose(ATP and NADP), water, and oxygen

Explanation: The water cycle shows the continuous movement of water within the Earth and atmosphere. System that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Then I does runoff and creates a new water source or goes back to a water source.

Mendel studied seven traits in pea plants. One of the monohybrid crosses he made was between plants with round seeds and plants with wrinkled seeds.
What was a conclusion Mendel drew from the F1 generation of this cross?
Explanation:
Traits are inherited in discrete units, and are not the results of "blending." ... traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1.
Answer:
The dominant factor, or allele, is for round seeds.
Explanation:
The factors (or alleles) don't disappear when two species are crossed, so "the factors or alleles for round seeds disappear completely from the plants" and "the factors or alleles for wrinkled seeds disappear completely from the plants" are both incorrect. From the drawing, we can see that the F1 generation is a round seed, meaning the dominant factor is for round seeds. Hope this helps!
What provides evidence of an increase in animal species at the same time that atmospheric oxygen concentrations increased?
ts fossil records but i need an explination
Answer:
Fossil records provide evidence of an increase in animal species at the same time that atmospheric oxygen levels increased.
Explanation:
A huge diversification among animal species occurred with the increase in the levels of atmospheric oxygen. The reason why the number of species increased drastically was that a whole new world opened up, the land. The land was open for exploitation and taking over, with every single niche free, so animals diversified and filled in pretty much all of the niches. The fossil records give us clues when this happened, as from only microorganisms there is a sharp rise in complex animals, coinciding with the increase of oxygen levels.
If it wasn't for the increase of atmospheric oxygen though this wouldn't have been possible. The oxygen in the atmosphere enabled animals to breathe on land. Also, it cooled off the global temperatures which were too high before the increase of atmospheric oxygen, making them suitable for life. And last but not least, the atmospheric oxygen resulted in the formation of the ozone layer, a layer that started to act as protection from the UV rays.
Answer:fossil record

When the Earth's continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation?
A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
B.) The continental crust was thicker and more dense. It sunk below sea level, separating land from water.
C.) The continental crust was thinner and less dense. It rose above sea level, separating land from water.
D.) The continental crust was thinner and more dense. It sunk below sea level, separating land from water.
I think it’s B, but I’m not completely sure. Help please!
Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
Explanation:
The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.
With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.
Answer:
Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
