True. A single cubic centimeter of the human brain consists of well-over 50 million nerve cells.
The basic structure of neurons is comparable to other cell types, despite the unique molecular, morphological, and functional characteristics of each kind of nerve cell. As a result, each nerve cell contains a cell body that houses the nucleus, endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, and other organelles that are crucial to the operation of all cells. The great magnification and resolution that the electron microscope offers are the ideal for identifying these features. The ability of nerve cells to specialise in intercellular communication makes them distinctive from other types of cells. This quality may be seen in their general morphology, the specialisation of their membranes for electrical transmission, and the intricate structural and functional details of their synaptic interactions with one another.

List and describe the four major parts of a flower. (Counts 20% of your lesson grade.)
Answer:
brainliest plssss
Explanation:
Filament
The filament is the thin tubular part of the stamen that extends and supports the pollen sac at the top.
Ovary
The ovary produces and contains unfertilized seeds. It sits centrally inside the flower at the base of the carpel. Once fertilized, it is the ovary that develops into the fruit of the plant.
Ovule
Ovules are contained within the ovary, and in the event of successful pollination, they will become the seed of the fruit.
Anther
The anther sits at the top of the filament of a stamen and produces and contains the pollen.
Bract
A bract works similarly to a sepal on plants that do not have sepals. It is a modified leaf that looks more like a petal than a leaf, as it is usually brightly colored and shaped differently to other leaves on the plant.
Style
The style is the elongated part of a carpel that joins the ovary to the stigma. It is the tube through which pollen is delivered to the ovary.
Stigma
The stigma sits at the top of the carpel, and its job is to capture pollen. It is often sticky in texture or contains tiny hair-like structures to help pollen adhere to its surface.
Receptacle
A receptacle sits at the top of a stalk underneath the main portion of the flower. It is often enlarged to support the weight of the flower, or the fruit when it develops. Its main function is to both connect the stalk to the flower and to support the flower.
Peduncle
A peduncle is the stalk of a flower, or the stem from which a cluster of flowers bloom.
Pedicel
A pedicel is the secondary stalk from which flowers grow off the main stem. Only plants that have inflorescence in the form of clusters or similar will have pedicels.
Perianth
A perianth is the scientific term for the parts of the flower that surround the reproductive organs. The perianth can be divided into two segments, the inner perianth and the outer perianth. The inner perianth is usually composed of the corolla, which is made up of a series of petals. The outer perianth is the calyx, which is typically made up of sepals. The purpose of the perianth as a whole is to protect the flower as it develops, protect the fully grown reproductive organs, and to lure pollinators to the flowers for the purpose of pollination and reproduction, ensuring the continuation of the species.
Calyx
The calyx is the technical term for a group of sepals, leaf-like structures that surround and protect the bud as it forms into a flower.

A living thing's cytosine and guanine levels are always equal.
What is guanine?One of the four primary components of DNA, guanine is an organic compound that contains nitrogen. Together, it and the DNA base cytosine form the hydrogen bonds that make up the rungs of the DNA double helix. RNA contains guanine, which is crucial for the integrity and proper operation of genetic material.
Two of the four nitrogenous bases that comprise DNA's structural constituents are cytosine and guanine. They are complementary base pairs that are consistently distributed equally throughout the DNA double helix.
This is so that the DNA molecule's double-helical structure and the hydrogen bonds that hold the two DNA strands together are preserved. The DNA molecule is stabilised by the pairing of cytosine with guanine and the other nitrogenous base pairs, adenine with thymine, to prevent mutations and maintain the accuracy and integrity of genetic information. In order for DNA to operate properly and genetic information to be maintained, an organism needs to have an equal amount of cytosine and guanine.

acute respiratory distress syndrome causes a protein-rich fluid to accumulate rapidly in the lungs. predict the consequences of this syndrome if medical intervention does not occur.
Acute respiratory distress syndrome causes a protein-rich fluid to accumulate rapidly in the lungs. The consequences of this syndrome if medical intervention does not occur is a decrease in oxygen which will cause ischemia.
The lungs are organs for exchanging oxygen and carbon dioxide gases as well as organs that play a role in blood circulation. Oxygen is needed for body activities as a raw material for making ATP in cells.Therefore the oxygen supply should not be stopped. Oxygen flows throughout the body through blood vessels.
ARDS or acute respiratory distress syndrome is a condition that occurs as a result of fluid buildup in the alveoli of the lungs so that only a little oxygen flows into the bloodstream. Blockage in the blood vessels can cause ischemia because the need for oxygen is not met because the blood supply throughout the body is reduced.

How is a neural impulse generated and transmitted from one neuron to another?
➤Neural impulses are electrochemical events. When a neuron is stimulated beyond a threshold level, there is a rapid shift in its polarity from a negative to a positive charge. This reversal of charge, called an action potential or neural impulse, is generated along the length of the axon to the terminal buttons.
➤When a neural impulse reaches the terminal buttons, it triggers the release of neurotransmitters, the chemical messengers that carry the message across the synapse to neighboring neurons. Neurotransmitters can have either excitatory or inhibitory effects on the neurons at which they dock.
A neural impulse, also known as an action potential, is generated and transmitted from one neuron to another through the following steps: Depolarization, Propagation, Threshold and Synaptic Transmission.
What happens during Depolarization?When a stimulus, such as a chemical messenger from another neuron, reaches the dendrites of a neuron, it causes the inside of the neuron to become more positively charged, a process known as depolarization.
What happens during synaptic transmission?At the end of the axon, the action potential triggers the release of chemical messengers, called neurotransmitters, into the synaptic cleft. These neurotransmitters bind to receptors on the dendrites of the next neuron, causing depolarization and triggering another action potential.

Reproductive barriers between closely related species include differences in mating behavior, gamete incompatibility, and developmental differences.
Reproductive isolation is the absence of gene flow between two populations or species, and it can be caused by various reproductive barriers that prevent interbreeding and the exchange of genetic material. Some examples of reproductive barriers between closely related species include: Differences in mating behavior, such as courtship rituals or mating calls, that prevent individuals of different species from recognizing or attracting each other as potential mates. Gamete incompatibility, which occurs when the sperm of one species cannot fertilize the eggs of another species, either due to differences in size, shape, or other physical attributes.

What is the type of allele interaction between gene variants?The type of allele interaction between gene variants makes reference to the dominance or absence of it for alleles of the same genetic loci, for example, in this case, if color is a codominant trait then the 100 % offspring will be spotted.
Therefore, with this data, we can see that the type of allele interaction between gene variants will determine the proportion of offspring.
