-Why do some land types absorb water better than others?
Answers
Answer:
I'm sure this is due to the porosity of the land type.
Explanation:
You see some land types are more porous than others; meaning, there are plenty air pockets in that land type. Hence, allowing water to pass through easily as compared to those with lesser air pockets.

This is an illustration of a typical food web. You might see a food web like this where you live. The organisms responsible for changing sunlight into food would be the Response area. Grass is one of these. You can see that the grasshopper and rabbit eat the grass and the bird and the shrew eat the grasshopper. Imagine that there was a big increase in the number of snakes in this area. We would then expect the Response area numbers to drop. In this food web, we consider the hawk a Response area. If the hawk population increases, we would see a drop in birds and shrews and snakes! The fungi and bacteria in the food web are examples of Response area. They break down any and all dead organisms. This helps to recycle matter.

MIGHT GIVE BRAINLIEST Compare a paramecium with a giraffe. How are their cells alike? How are they different? Write
your answer in complete sentences. be original
Answers
Answer:
A paramecium is similar to a giraffe in one defining way. Both a giraffe and paramecium have eukaryotic cells. One way in which the two are different is that the paramecium feeds on decaying organisms, whilst a giraffe eats leaves. Another is that paramecium primarily live in fresh water, while a giraffe dwells on land.
A paramecium and a giraffe are two very different organisms. A paramecium is a single-celled organism, while a giraffe is a large, multicellular mammal. Despite their many differences, both a paramecium and a giraffe have cells. However, the cells of a paramecium and a giraffe are quite different from each other in terms of size, shape, and function.
One of the most significant differences between the cells of a paramecium and a giraffe is their size. The cells of a paramecium are very small, measuring only a few micrometers in diameter. In contrast, the cells of a giraffe are much larger and more varied in size, depending on their function within the body. For example, giraffe nerve cells are much larger than giraffe red blood cells.
Another important difference between the cells of a paramecium and a giraffe is their shape. The cells of a paramecium are typically elongated and oval-shaped, with a pointed end at one end and a rounded end at the other. In contrast, the cells of a giraffe are much more varied in shape, depending on their location and function within the body. For example, giraffe muscle cells are long and cylindrical, while giraffe nerve cells are elongated and have many branching extensions.
Despite their many differences, the cells of a paramecium and a giraffe do have some similarities. For example, both types of cells have a cell membrane that surrounds the cell and controls the movement of materials in and out of the cell. Both types of cells also have a cytoskeleton, which provides support and structure to the cell. Additionally, both types of cells have a nucleus, which contains the cell's genetic material.
Overall, while the cells of a paramecium and a giraffe have some similarities, they are also very different from each other in terms of size, shape, and function. The small, simple cells of a paramecium are adapted for life in a single-celled organism, while the larger, more complex cells of a giraffe are adapted for life in a multicellular mammal.

identify each of the cell structures and their function: centrosomes, aster, equator, cleavage furrow, cell plate, kinetochore fibers, spindle, microtubules and cytokinesis
Answers
Answer: Interphase
Explanation:
aster- they hold the two centrioles at the two opposite poles, and help the spindle apparatus to position during nuclear division.
equator- it divides the planet into a northern hemisphere and a southern hemisphere.
cleavage furrow- is an indentation that appears in a cells surface when the cell is preparing to divide.
cell plate- a plate that develops at the midpoint between the two groups of chromosomes in a dividing cell and that is involved in forming the wall between the two new daughter cells.
kinetochore fibers- the main function is to generate load-bearing attachments of sister chromatids to spindle microtubules during cell division.
spindle- is used to ensure the chromosomes are positioned properly inside the cell during mitosis.
microtubules- they regulate cell growth and movement, as well as key, signaling events which modulate fundamental cellular processes.
cytokinesis- the process by which one’s self physically divides into two cells.

What best describes ribosomes?
Answers
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.
Answer:
A ribosome is a intercellular structure made of RNA and protein

Answers
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.
Which statement describes one of Wegener’s ideas that contributed to the theory of continental drift?
The continents drifted apart due to repeated meteor impacts.
The continents were once connected as one landmass.
The continents have moved apart very quickly due to earthquakes.
The continents are magnetically pulled toward or pushed away from one another.
Answers
Answer:
Option B
The continents were once connected as one landmass.
Explanation:
The theory of continental drift suggests that all the continents on the planet were once connected, forming a supercontinent. However, over time they drifted apart as a result of some internal forces of the earth.
The most appropriate option that shows this is option B: The continents were once connected as one landmass.
This statement describes one of Alfred Wegener's ideas that suggests that a very long time ago, the continents were once connected in a landlocked mass. The fact that the continents are separated now shows that the continents are continuously shifting position on the earth's surface.

MITOSIS:
Mitosis is the process whereby a single cell results in two daughter cells that are genetically identical to one another.
Mitotic division occurs in stages namely: prophase, metaphase, anaphase and telophase.
Prophase: Condensation of chromatids to more visible X-shaped structure called chromosomes.
Metaphase: Chromosomes line up at the cell's equator
Anaphase: Chromosomes are pulled apart by the spindle fibers that attached to their centromere.
Telophase: Reformation of the nuclear membrane.
According to this question, in the anaphase stage, spindle fibers start to pull away from the center of the cell to separate the chromosomes.

Explain the difference between 'magnetic' and 'magnetised'
Answers
Answer:
Magnetic refers to a material's ability to produce a magnetic field. All magnets are magnetic, but not all materials are magnetic. Some common examples of magnetic materials include iron, nickel, and cobalt.
Magnetized, on the other hand, refers to a material that has been subjected to an external magnetic field, causing the material's electrons to align and produce a magnetic field of their own. This magnetic field will persist even after the external magnetic field has been removed. So, a material can be magnetic and not magnetized, or it can be magnetic and magnetized.
Explanation:
In summary, magnetic refers to a property of a material, while magnetized refers to a state of a material that has been subjected to an external magnetic field.
