How might it benefit an organism to have the nucleus near the centre of its cells?
Answer:
For protection and better control.
Explanation:
First of all, if the nucleus was located in the periphery it would be easier for physical damage to reach it, but also for viruses or so, even with the use of vectors. Then, being in the center makes it equally easier to send signals, orders or RNA to each part of the cell.

In what form does the human body store excess sugar? In what form do plants store excess sugar?
I AM SO CONFUSED...HELP?
The human body stores excess sugar as glycogen, mostly in the liver and muscles. On the other hand, plants retain their excess sugars as starch in specific organs like tubers or bulbs.
Explanation:The human body and plants have a unique way of managing excess sugar, which is useful for future energy needs. In humans, the body stores excess sugar in the form of glycogen.
This process occurs within the liver and muscles. Conversely, in plants, sugar is stored as starch.
This starch is often held within special organs like tubers or bulbs and can be converted back into sugar when the plant needs energy.

Which layer of soil is least likely to be penetrated by plant roots? a. O (organic matter) b. A (topsoil) c. B (subsoil) d. C (parent rock)
Answer: d. C (parent rock)
Soil horizons are the layers lying parallel to the surface or subsurface layers of soil. These horizons are formed in the process of soil horizon. These sequence of soil horizons is collectively called as soil profile.
The layer or soil horizon, which is least likely to be penetrated by plant roots is C horizon. The C horizon is a layer of soil, which consists of huge aggregates of parent rocks, which are unweathered or partially weathered, lying deep in the bottom of the soil profile. It does not contain organic matter. Also, the texture of the soil is not fine, instead hard rocks are present. Therefore, this layer of soil cannot be penetrated by plant roots.
what societal needs were addressed by science in the ancient world
Like in present, many of the ancient civilizations studied biology. They also came to know about the natural phenomenon and utilized that information to meet the requirements of the society. The herbal medicines were used by Asian civilizations, also the South American civilizations created agricultural methods like irrigation and crop domestication.
The Greek civilizations are well-known in making substantial contributions to the emergence of life science. They are accredited with developing the fundamental guidelines of modern science. School of medicine was established during 400 BCE by the Greek physician Hippocrates. Even the first classification for living species is credited to the Greek philosopher Aristotle.
In terms of biological function or process, what do the solid arrows shown in Model 2A represent?
Solid arrows in the models typically represent direct interactions or processes such as regulatory activations, substrate binding, electron movement, and carbon fluxes in biological systems. They indicate the direction of process flow and are used to depict regulatory networks, biochemical reactions, and synthetic pathways.
In terms of biological function or process, the solid arrows shown in different models represent various types of interactions and processes. Direct interactions such as regulatory steps, substrate binding, or energy changes are examples of these functions. The solid arrows often indicate the direction of process flow, such as activation in regulatory networks, electron movement in biochemical reactions, substrate or ion transport across a membrane, natural carbon fluxes in ecosystems, or direction of chemical and biological pathways for synthesizing macronutrients. Positive interactions or activations are typically indicated by an arrow pointing from the activator to the target, as seen in signal transduction pathways.

Gametes from two plant species combine and produce a haploid zygote, and that zygote develops into a haploid, hybrid plant. why is the hybrid plant sterile
The hybrid plant is sterile due to its haploid nature, as it possesses only a single set of chromosomes. This prevents it from undergoing regular meiosis and producing viable gametes, resulting in sterility.
Explanation:The hybrid plant is sterile because it is haploid, meaning it has only one set of chromosomes. As a result, it is unable to undergo regular meiosis to produce viable gametes. During meiosis, chromosomes pair up and exchange genetic material. However, in a haploid plant, there are no pairs of chromosomes to engage in this process. Due to the lack of chromosomal pairs and thus a lack of genetic diversity in the gametes, the hybrid plant is sterile.

The sterility of a hybrid plant resulting from the combination of gametes from two different plant species is often attributed to a phenomenon known as hybrid sterility or gametic incompatibility.
Chromosome Number Incompatibility: Different plant species may have different numbers of chromosomes or different arrangements of genes on their chromosomes.
When gametes from two different species combine during fertilization, the resulting zygote may have an abnormal chromosome number or structure, leading to problems in meiosis during subsequent cell divisions.
Meiotic Irregularities: During meiosis, the process that produces gametes, chromosomes from each parent are supposed to pair and separate properly. In hybrids, meiotic irregularities may occur, resulting in the formation of non-functional or incomplete gametes.
These irregularities can lead to the production of aneuploid cells (cells with an abnormal number of chromosomes) in the hybrid plant.

How many calories are provided by a food that contains 20 grams of carbohydrate, 8 grams protein, and 5 grams of fat?
a. 232
b. 378
c. 157
d. 258
e. 558?
Calories are used in defining the unit of the food that gives energy to the body. Food containing 8 grams of protein, 20 grams of carbohydrate, and 5 grams of fat provides 157 Calories. Thus, option c is correct.
What are calories?Calories are defined as the energy provided by the various molecules for the food that needs to be maintained so as not to get obese or underweight. Food containing carbohydrates, fats, and proteins is used to evaluate the calories.
The calories for the food containing this organic molecule are calculated as:
C= 4 carbohydrates + 9 fats + 4 proteins
Given,
Carbohydrate = 20 gm
Fats = 5 grams
Proteins = 8 grams
Substituting the values above as:
Calories = (20) × 4 + (5) × 9 + 4 × (8)
= 80 + 45 + 32
= 157 calories
Therefore, option c. 157 calories are present in the given food.

Which lobe or cortex is farthest from the cerebellum?
a. frontal
b. parietal
c. occipital
d. temporal?
Final answer:
The frontal lobe, located at the front of the brain, is the cerebral cortex furthest from the cerebellum.
Explanation:
To determine which lobe or cortex is farthest from the cerebellum, it is important to understand the location of each lobe of the cerebral cortex. The cerebellum is located beneath the occipital lobe, towards the back of the brain. Considering the position of each lobe, the frontal lobe is located in the forward part of the brain and is the farthest lobe from the cerebellum. Therefore, the correct answer is a. frontal.
