Answer: Oval.
Explanation:
The nucleus of a cell is a membranous structure normally found in the center of eukaryotic cells and is where most of the cellular genetic material is found, organized in DNA molecules (deoxyribonucleic acid) associated with proteins such as histones, which make up the chromosomes.
The function of the nucleus is to maintain the integrity of the genes in the DNA and to regulate gene expression to control cellular activities. It then controls when DNA is transcribed into RNA (ribonucleic acid) and when it is exported to the cytoplasm to be translated into proteins.
The nucleus is composed of a nuclear envelope consisting of a double membrane that surrounds it, as well as pores that allow the passage of RNA for the regulation of gene expression.
The cells of the inner cheek are classified as non-keratinized stratified squamous epithelium. An epithelium is a tissue made up of joined cells that line the outer surface of the body and inner organs. Squamous cells are flat, scale-like, whereas stratified cells are arranged in multiple layers. Non-keratinized means that the cells constitute soft tissue found in the moist parts of our body, such as the mouth, stomach, among others. In a normal healthy cell, the nucleus is uniformly stained, oval in shape and smaller in relation to the cytoplasm.

A climate zone is an area that is defined by two main factors. What are they?
Temperature and weather
Precipitation and climate
Weather and climate
Temperature and precipitation
Answer:
Temperature and precipitation.
Explanation:
Climate is defined as long-term climate patterns in a location. Looking at average temperature and precipitation through time is the simplest way to characterize the climate.
Temperature and precipitation are the two most significant factors in the climate of a place. Obviously, the annual average area temperature is significant, but the annual temperature range is important as well. Some locations range from the highest to the lowest temperature significantly wider than others. Average precipitation is very essential, but the annual change in precipitation is equally important. Some regions experience approximately the same precipitation year-round. For half of the year, other locations have very low precipitation while the other portion of the year has lots of precipitation.

In graph two, label A represents the gases hydrogen sulfide, methane, and carbon dioxide. What gases are represented by label B and how do these gas levels relate to the evolution of photosynthetic organisms?
Answer:
Oxygen.
Explanation:
Oxygen is the gas that is increased in concentration due to photosynthetic activities of plants and algae because in the process of photosynthesis, plants and algae absorb carbondioxide gas into the body and as a result, oxygen gas is produced. Some amount of oxygen is used by the plants in the process of respiration while the remaining is released in the atmosphere through stomata.
During which process is mRNA converted into a sequence of amino acids for protein production?
transcription
translation
DNA replication

Answer:translation
Explanation: Translation is the process by which nucleotide sequence of mRNA (messenger ribonuceic acid) is converted into the amino acid sequence
Answer:
B translation
Explanation:
because it is a process in which an mRNA molecule is used to assemble amino acids into polypeptide chains.
When does chromatin form into chromosomes?
Answer:
Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromatin is located in the nucleus of our cells. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus.

Which of the following is NOT true of
autotrophic protists?
A. these organisms can start food chains as producers
B. examples are like phytoplankton, dinoflagellates, and euglena
C. they feed off of other organisms
Answer:
C. they feed off of other organisms
Explanation:
Autographs, as the word auto suggests (auto : self) , produce their own food. So they wont feed on other organisms for their survival.
Therefore, option C is incorrect and since we have to find the incorrect option that is the answer.
Answer: C. they feed off of other organisms

How can the peak of Mount Kilimanjaro be glacial when it is located so close to the equator?
Answer:
Explanation:
Mount Kilimanjaro lies just 205 miles from the equator, in the country of Tanzania. ... as they thought it was impossible for ice to form so close to the hot, equatorial sun. ... Mawenzi is a craggy peak that ranks as the third highest peak in Africa, after Kibo ... However, Kibo is considered a dormant volcano; it can erupt again!
on which surfaces was there more friction? how did you reduce the friction on objects?
Answer: Rougher surfaces have more friction between them than smoother surfaces. That's why we put sand on icy sidewalks and roads. You can't slide as far across ice with shoes as you can on the blades of skates (see Figure below). The rougher surface of the soles of the shoes causes more friction and slows you down.
Explanation:
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force.

Why doesn't the level of oxygen in the atmosphere decreases'?
Answer:
Oxygen levels are decreasing globally due to fossil-fuel burning. The changesare too small to have an impact on human health, but are of interest to the study of climate change and carbon dioxide.

The atmosphere is constant for many years does not decrease because the green plants which are capable of photosynthesis take up CO2 from the atmosphere and produce 0 2 in return
Which direction do
rock fragments eroded
by runoff generally
travel?
A downhill
B uphill
C uphill at certain times
of the day and
downhill at other
times of the day
D horizontally until
they reach an
obstacle that they
cannot pass over
Answer:
A downhill
Explanation:
A runoff happens when water drags sediment from a rock over a sloping terrain. Thus, water drags the eroded fragments of a rock in favor of gravity, pushing these fragments downwards. This is very common in mountainous and steep regions, without vegetation cover, where erosion caused by runoff is very high.

Why do you think it is functionally important that the bones of the os coxae fuse together rather than remain independent bones
Answer:
Provides more strength.
Explanation:
It is functionally important that the bones of the os coxae fuse together rather than remain independent bones because the fusion of bones of the os coxae increases their strength and they can perform their function very well. If the fusion of bones of the os coxae did not occur and they remain independently so they can't bear the load of the body and so the function is also adversely affected.

Answer:
The correct answer is - protist.
Explanation:
Protist is a single-celled eukaryote that contains organelles. It is the last common ancestor of all animals as is consider as most primitive animal cells as it has no cell wall but contains the nucleus and other double-membrane organelles. The protists are the cell that distinguishes fungus, plant cells, and animal cells into these three different kingdoms.
