Which is true about all unicellular and multicellular organisms?
•They are made of one cell
• They reproduce
• They cause infections
• They are made of multiple cells
Answer:
they both reproduce
Explanation:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
the ________ extends through the hindbrain, midbrain, and forebrain
The structure that is common to hindbrain, midbrain and forebrain is reticular formation.
Further Explanation:
The spinal cord and brain are two major parts of the central nervous system. Nerve cells that are soft and spongy make up the brain. The brain is divided into three major parts:
• Hindbrain
• Midbrain
• Forebrain
In the brain, brain stem, cerebrum, and cerebellum are also present. The link between the brain and spinal cord is made up of the brain stem. In the brain stem, reticular formation is present. It is nothing but a group nuclei present inside the brain stem. They are extending throughout the midbrain, hindbrain, and forebrain. It mainly plays a significant role in arousal and consciousness. The tegmentum of the brain stem contains a complex network of interconnected circuits of neurons, which is associated with the reticular formation.

In the context of TCS (Time/Temperature Control for Safety) foods, the food option from saltine crackers, canned peaches, cooked beans, and raw carrots that are considered a TCS food is the cooked beans.
This is due to their high protein content and moisture which can promote the growth of harmful bacteria if not stored correctly.
Explanation:In the query about TCS foods, TCS stands for Time/Temperature Control for Safety.
These foods require specific time and temperature controls to prevent the growth of pathogens or production of toxins. From the listed foods: saltine crackers, canned peaches, cooked beans, and raw carrots, the cooked beans fall under the category of TCS foods.
This is because they are protein-rich and moist, providing a favorable environment for pathogen growth if not stored correctly. On the other hand, saltine crackers, canned peaches, and raw carrots are not TCS foods because they do not typically support the growth of harmful bacteria or toxins due to their low moisture content, high acidity or process of preservation.

A cell with a predominance of smooth endoplasmic reticulum is likely specialized to ________.
The right answer is synthesize large quantities of lipids.
It should be known that there are two types of endoplasmic reticulum: rough (contains ribosomes) and smooth (does not contain ribosomes).
The rough endoplasmic reticulum harvests in its light the proteins synthesized by the ribosomes attached to its surface. The proteins then move inside the light to be eventually transported to the Golgi apparatus, where they will complete their maturation and be distributed to the different compartments of the cell.
The smooth endoplasmic reticulum carries, associated with its membrane, the enzymes necessary for the synthesis of lipids and lipoproteins (molecules associating a protein part and a lipid part). Very reduced in the majority of cells, the smooth endoplasmic reticulum is very extensive in cells specialized in the synthesis of lipids (adipocytes) or in that of lipoproteins (hepatocytes for example).
A cell with a predominance of smooth endoplasmic reticulum is likely specialized to synthesize large quantities of lipids.
The smooth endoplasmic reticulum is part of the endomembrane eukaryotic system.
The smooth endoplasmic reticulum is an organelle composed of a three-dimensional (3D) network of interconnected tubules and cisterns.
This organelle (smooth endoplasmic reticulum) is responsible for the synthesis and storage of lipids such as cholesterol and phospholipids.
In conclusion, a cell with a predominance of smooth endoplasmic reticulum is likely specialized to synthesize large quantities of lipids.

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.

The myocardium is thickest in the ________ ventricle because it must work the hardest to pump blood to the entire body.
The myocardium is thickest in the left ventricle as this part of the heart must pump blood to the majority of the body, requiring a thicker muscular wall due to the exerted pressure.
Explanation:The myocardium is thickest in the left ventricle because it must work the hardest to pump blood to the entire body. The myocardium is the muscular wall of the heart, and it contracts to push blood out of the heart. The left ventricle has to pump blood to all parts of the body, except the lungs, exerting more pressure and needing a thicker myocardium as a result.

How would planting a variety of plants in a vacant lot help establish an ecosystem in that location?
Plants grow and reproduce together, producing nutrients from leaves / branches, encouraging insects, along with animals and a keystone species, to establish a revolving ecosystem.
What is an ecosystem ?An ecosystem is a geographical area in which plants, animals, and other species, as well as weather and scenery, coexist to produce a life bubble. Abiotic variables, or nonliving components, coexist with biotic components in ecosystems. Plants, animals, and other species are considered biotic factors.
Plants capture solar energy through photosynthesis, giving other organisms food and a place to live. For instance, insects that feed on plants may be eaten by birds that in turn may be devoured by raptors, and so on.
Therefore, planting a variety of plants in a vacant lot help establish an ecosystem in that location.

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.

The fully folded structure of a functional protein composed of a single polypeptide chain is referred to as the _____ structure.
True or false? The structures inside a cell are suspended in a system of microscopic fibers called cytoplasm
False, cells are structured by the cytoskeleton, not the cytoplasm. Cytoplasm contains the organelles and cytoskeleton, which includes microfilaments and microtubules. The cytoplasm isn't green, and the nucleus doesn't house cytoplasm but nucleoplasm.
True or false? The structures inside a cell are suspended in a system of microscopic fibers called cytoplasm - Thisstatement is false. The structures inside a cell are indeed suspended, but not in the cytoplasm itself. They are suspended in a network of protein fibers within the cytoplasm, known as the cytoskeleton. The cytoplasm is the fluid that fills the cell and contains the organelles, but it is the cytoskeleton that provides structure.
The cytoplasm is not made of cells; rather, it is the gel-like substance within the cell membrane that holds all the cellular components, including the cytoskeleton and organelles, excluding the nucleus. Two types of cytoskeletal structures are microfilaments and microtubules. Microfilaments are also known as actin filaments, which are crucial for cellular movement and structure, while microtubules help maintain cell shape and are involved in intracellular transport.
Regarding the false statements: The cytoplasm is not usually green, this color is typically associated with chlorophyll found in plant cells. Also, the nucleus of a cell is not filled with cytoplasm; instead, it contains a substance called nucleoplasm.
