What has no nucleus and a large surface area?
Answer:
prokaryotic cells
Explanation:
a example of a prokaryotic cell would be a blood cell they have no nucleus and a large surface.
Answer:
The answer would be Prokaryotic Cells
Explanation:
A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles. These Prokaryotic cells are not divided up on the inside by membrane walls, but consist instead of a single open space.
The majority of prokaryotic DNA is found in a central region of the cell called the nucleoid, and it typically consists of a single large loop called a circular chromosome. So technically these cells lack nucleuses, while still containing genetic material(s).

Seafood Watch recommends which seafood _______.
a. to buy or avoid
b. to catch and sell
c. to harvest sustainably
d. is safe to eat
Answer:
a
Explanation:
to buy or avoid
Seafood Watch recommends which seafood to buy or avoid. Thus, option A is correct.
What is seafood?Seafood is food obtained from the sea. Unsustainable fishing methods, such as dragging and dynamite fishing, entrap or kill various species that are not necessarily targeted by the fishing industry. By identifying varieties of seafood that have been caught sustainably, Seafood Watch promotes them over those that have not.
The theory is that since only fisherman who employ sustainable practices are financially rewarded, they will outperform rivals. Based on rigorous scientific standards for environmental sustainability, our Seafood Watch program assigns grades to seafood collected or raised all around the world.
Our suggestions can be used by customers and business owners to locate seafood that has been farmed sustainably. Numerous species are included in the exhaustive list, along with information about where in the water they were caught—from the wild or from farms—and how they were harvested.
Therefore, Seafood Watch recommends which seafood to buy or avoid. Thus, option A is correct.

Which region is located between 60-90N and 60-90S?
Mid-Lats
Polar
Tropics
Tropical Rainforest
Answer:
The correct option is Polar
Explanation:
The polar region/arctic are located/extend from 66.5 degrees N (north) and also S (south) latitude to the north and south poles of the earth. From this, it can be deduced that the polar region is located between 60-90 degrees of N and 60-90 degrees of S. Polar regions are far from the equator as a result of this and are characterized by very low solar radiation.
Polar or artic region is located between the coordinates 60-90N and 60-90S. The polar regions are extremely far away from the equator, which is situated at 0-degrees latitude.
The correct answer is:
Option B. Polar
The polar region is defined as the region situated 60-degrees north or south of the equator. The solar radiation in the polar region ranges from only 18 hours and 5 hours during winters.
The middle latitudes are situated between 30N and 30S of the equator. It is characterized by moderate sunlight.
Tropics or tropical rainforests are situated near the equator and usually experience a warm climate.
Therefore, option B is correct.

How does niche affect organisms populations in an ecosystem
Answer:
Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.
Explanation:
A species' ecological niche can be defined as the range of resources and conditions allowing the species to maintain a viable population a more simple definition is if two species have the same niche, one species will exclude the other.

Sugar
Explanation:
I am not completely sure but correct me if I am wrong. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells.

A pair of fruit flies reproduces and has 1000 offspring. All 1000 offspring have the alleles Gg. What is the most likely combination of alleles that each parent has, and why are other combinations not likely.
Answer:
The correct answer would be - GG and gg.
Explanation:
As it is given that all the 1000 offspring having the same allele Gg which is only possible in one condition that is cross between GG and gg because it is a heterozygous condition in the offspring. So there must be both allele present and it can not be heterozygous parents as there would be a different combinations of offspring in that case.
If the parents either GG only all the offspring would be GG the same with gg than all the offspring will be gg, thus the correct answer would be GG and gg.

A) prokaryotic
B) eukaryotic
C) unicellular organisms
D) stem cell
Stem cell term applies to muscle cells.
What are the functions of stem cells?Stem cells are the cells that develop into blood, brain, bones, and all of the body's organs. They have the potential to repair, restore, replace, and regenerate cells, and could possibly be used to treat many medical conditions and diseases.
While they can regenerate themselves in an animal or person they are generally very difficult to grow and to expand in the laboratory. Because of this, it is difficult to obtain sufficient numbers of many adult stem cell types for study and clinical use.
Stem cells originate from two main sources: adult body tissues and embryos. Scientists are also working on ways to develop stem cells from other cells, using genetic “reprogramming” techniques.

Which correctly describes the role of histones in eukaryotic cell division?
a) Histones connect sister chromatids.
b) Histones protect the ends of chromosomes.
c) Histones keep the DNA compact and organized.
d) Histones copy the DNA before division begins.
Histones copy the DNA before division begins is the correct role of histones.
What is Histone?A chromosome's structural support is provided by a protein called a histone. Long DNA molecules found on each chromosome must fit into the cell nucleus.
To do it, the DNA wraps around complexes of histone proteins, giving the chromosome a more compact form. Additionally, histones are involved in the control of gene expression.
A nucleosome, which is made up of eight histone proteins, can exist. DNA can loop around a nucleosome much like a small spool. Thus, histones are crucial in maintaining the genome's order and neat wrapping inside a cell.
Therefore, Histones copy the DNA before division begins is the correct role of histones.
