Are large organisms such as redwood trees and elephant large because they contain extra large cells or just more standard size cells. Explain How
Answer:
Larger organisms have the same size cells as we do. They just have many more of them.
Explanation:
Hope this helps!
Due to their size, they contain more regular cells, which aids in the organism's functioning.
What is a cell?The smallest unit in biology that can sustain life on its own and makes up all living things as well as the body's tissues.
After using a very early microscope to examine a piece of cork, Robert Hooke proposed the name "cell" in 1665, derived from the Latin cella, which means "storeroom or chamber."
It is also claimed that he believed the rectangular spaces resembled some monastic cells.
The size of the cells is constant throughout all creatures. A rat's cells won't be bigger than an elephant's. Compared to the number of cells in a rat, it contains more cells. However, the cells are all the same size.
Thus, large organisms such as redwood trees and elephant large as they contain more standard size cells.

Someone please help me with Punnett square
Answer:
1. Phenotype ratio = 3:1
Genotype ratio = 1:2:1
2. Phenotype ratio = 4:0
Genotype ratio = 4:0
3. Phenotype ratio = 1:1
Genotype ratio = 1:1
Explanation:
According to this question, a gene coding for tallness is involved. The allele for tallness (T) is dominant over the allele for shortness (t). The phenotype and genotype ratio of each parental combinations is given in the attached punnet square.
1. Tt × Tt
In this cross, both parents (Tt) will produce T and t gametes. Using this in a punnet square, the offsprings will be as follows: TT, Tt, Tt, and tt. Hence, The phenotype ratio is 3 tall: 1 short while genotype ratio is 1(TT): 2(Tt) : 1(tt).
2. TT × tt
In this cross, TT will produce T gametes while tt will produce t gametes. Using this in a punnet square, all offsprings will be heterozygous "Tt". Hence, The phenotype ratio is 4 tall: 0 short while genotype ratio is 4 (Tt) : 0 (tt).
3. tt × Tt
In this cross, tt will produce t gametes while Tt will produce T and t gametes. Using this in a punnet square, the following offsprings will result: Tt, Tt, tt and tt. Hence, The phenotype ratio is 1 tall: 1 short while genotype ratio is 1(Tt) : 1(tt).
What might explain why light travels in a straight line? Group of answer choices If there is nothing to interfere with light waves, they should travel in a straight line. Light waves will always travel in a straight line, even if they come into contact with another object. Light waves don't travel in a straight line. Light waves travel in a straight line because sound waves travel in a straight line.
Answer:
A. If there is nothing to interfere with light waves, they should travel in a straight line.
Explanation:
A light wave is a transverse wave, and do not require material medium for its propagation. It travels in straight lines in all directions from the source.
Light waves travel in straight paths (a principle referred to as the rectilinear propagation of light) known as rays, of which the combination of two or more rays gives a beam of light. When there is an obstruction on or interference with the path of light, it stops traveling in a straight line due to either absorption, refraction or diffraction.
When light from a source is forced to travel in one direction only, it is said to be polarized.
What two gases make up most of the atmosphere?
Answer:
Using the slope-intercept form, the slope is −35 . The equation of a perpendicular line to y=−3x5+3 y = - 3 x 5 + 3 must have a slope that is the negative reciprocal of the original slope
Answer:
Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2).

Why did linnaeus classify organisms on the basis of appearance
Answer:
Under Linnaeus's system, every species is known by a unique Latin-sounding genus and species name that distinguishes it from other species. Linnaeus"s work organized organisms into logical classes based on their appearance and characteristics and thus provides a basis for comparing different species.

How ocean trenches and mid-ocean ridges formed?
Answer:
Explanation:
The oceanic lithosphere is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at ocean trenches. ... A process previously proposed to contribute to plate motion and the formation of new oceanic crust at mid-ocean ridges is the "mantle conveyor" due to deep convection

Overproduction results in more individuals in a population than the resources can support. What does this cause?
Answer:
Explanation:
Overproduction result in when populations produce more progeny which has the ability to live and survive all through the reproductive age. Overproduction lead to competition.
Competition occur as a result of too much population on a limited resources. Because the population is more than the resources, organisms tend to compete for food, nesting , space, nest which affect their ability to reproduce successfully and also survive.
Answer:
It causes competition

True or False: Plate tectonics affect ocean current
movements, which alters the global climate.
Answer:
True
Explanation:
True. Plate tectonics in the movement of continents over the course of millions of years. This can affect both global and local patterns of climate and atmosphere-ocean circulation. The position of the continents determines the geometry of the oceans and therefore influences patterns of ocean circulation. The locations of the seas are important in controlling the transfer of heat and moisture across the globe, and therefore, in determining global climate.

how does the coriolis effect affect the weather
Answer:
Explanation:Weather Patterns
In the Southern Hemisphere, currents are deflected to the left. As a result, storm systems seem to rotate clockwise. Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles.
Why are antibodies specific in function?
Answer:
I like to think of antibodies as a lock and key, there is a specific key needed for each locks. Antibodies recognize foreign invading microorganisms by specifically binding to a pathogen's antigens and neutralizing them.
Explanation:
Animal cells are considered eukaryotic, and bacteria cells are considered prokaryotic. The difference between these two cell types is that–
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.
