Answer:
meiosis
Explanation:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

How do plasmodesmata affect the individuality of the cells?
Answer:
[tex]{\fcolorbox{blue}{black}{\blue{answer}}}[/tex]
Plasmodesmata play roles in both cellular communication and in molecule translocation. Plant cells must work together as part of a multicellular organism (the plant); in other words, the individual cells must work to benefit the common good. Therefore, communication between cells is crucial for plant survival.
Since Asha is a healthy woman in her fortles, she does not have Niemann Pick
disease type A. For this question, assume that she is a healthy person who is a
carrier. If Asha is a carrier of the allele for Niemann Pick disease type A, what is het
genotype?
Answer:
By the definition of "carrier," Asha does not exhibit any physical features (phenotype) of the Nieman-Pick disease, but she carries an allele for this disease. In order for this to be possible, Asha must carry a autosomal dominant allele for this gene to mask the effects of carrying an allele for the.
Explanation:
By the definition of "carrier," Asha does not exhibit any physical features (phenotype) of the Nieman-Pick disease, but she carries an allele for this disease.
write a hypothesis on which lizard parent (long legs or short legs) will travel the greater distance? why?
Answer:
I believe that the lizards from the two populations, both short legged and long legged will still mate and reproduce. First of all, the lizards are still of the same species. Secondly, the lizards would mate and reproduce because it will increase their species chances of survival. In general, any chance of increasing survival rates will be taken in any natural circumstance.

How do plants get glucose they need for cellular respiration?
Answer:
Plants make glucose by photosynthesis During cellular respiration, glucose combines with oxygen to release energy and to form carbon dioxide and water.

Explain how respiration and cellular respiration are not
the same thing
Answer:
reathing involves inhale of oxygen from the atmosphere into the lungs and exhale of carbon dioxide from the lungs into the atmosphere ; whereas cellular respiration involves breakdown of glucose into carbon dioxide and water in living cells, releasing energy.
Explanation:
Why are niches important to
ecosystems?
Answer:
Ecological niches allow species to exist in their environment. Under the right conditions, the species will thrive and play a unique role. Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.
If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.

Global warming is causing atmospheric CO2 levels to increase, which is expected to cause ocean acidification Which of the following is NOT a consequence of increased atmospheric CO2 levels?
a) decrease in the concentration of bicarbonate ions in the oceans
b) increase in the amount of carbonic acid formed in the oceans
c) decrease in the amount of calcium carbonate produced in the oceans
d) decrease in the concentration of carbonate ions in the oceans
e) increase in the concentration of hydrogen ions in the oceans
Answer:
This might not sound like much, but the pH scale is logarithmic, so this ... The ocean absorbs about 30% of the carbon dioxide (CO2) that is released in the atmosphere. As levels of atmospheric CO2 increase from human activity such as burning ... track and forecast ocean acidification, warming and other important ocean
An increase in atmospheric CO2 levels does not cause a decrease in the concentration of bicarbonate ions in the oceans.
WHAT IS OCEAN ACIDIFICATION?
Ocean acidification is the decrement in pH level of the ocean due to the absorption of carbon dioxide (CO2). Carbon dioxide is a gas that reacts with water to form carbonic acid (H2CO3), which makes the water acidic or have a low pH.CONSEQUENCE OF CO2 ABSORPTION IN OCEANS:
An increased CO2 level in the atmosphere means that the rate at which the ocean will absorb the atmospheric gas will it increase. Since CO2 is said to make the ocean acidic, the following will likely occur to increase acidity of the ocean:
Increase in the amount of carbonic acid (H2CO3) formed in the oceansDecrease in the amount of calcium carbonate (CaCO3) produced in the oceansDecrease in the concentration of carbonate ions (CO32-) in the oceansIncrease in the concentration of hydrogen ions (H+) in the oceansN.B: Bicarbonate ion (HCO3-) causes acidity, hence, the decrease of bicarbonate ions cannot be a consequence of ocean acidification.

list 2 object that produce gamma rays in space
Answer:
object number 1: SOURCES OF GAMMA RAYS
object number 2: COMPOSITION OF PLANETS
Explanation:
Sources of Gamma Rays: Gamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes. On Earth, gamma waves are generated by nuclear explosions, lightning, and the less dramatic activity of radioactive decay.
Composition Of Planets: Scientists can use gamma rays to determine the elements on other planets. The Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) Gamma-Ray Spectrometer (GRS) can measure gamma rays emitted by the nuclei of atoms on planet Mercury's surface that are struck by cosmic rays. When struck by cosmic rays, chemical elements in soils and rocks emit uniquely identifiable signatures of energy in the form of gamma rays. These data can help scientists look for geologically important elements such as hydrogen, magnesium, silicon, oxygen, iron, titanium, sodium, and calcium.

rank from largest to smallest and explain what these structures are: allele, chromosome, gene
Answer:
Chromosome, Gene, Allele

Where do new adaptations come from? There is more than one correct answe
choose all that apply!!
New combinations of genes from the parents
Nature will give an organism the adaptations it needs to survive
An organism can choose to grow an adaptation
Mutations in the DNA passed on to an organism
Answer:
new adaptations come from:
New combinations of genes from parents.
Mutations in the DNA passed on to an organism.
Explanation:
Mutations in the DNA passed on to the organism and bring adaptations in the form of new characteristics. mutations may b lethal or fruitful and develop new characteristics in an organisms and increase its survival.
new combinations of genes from parents results from crossing over and recombination. these new genetic combinations bring adaptations.
