What do you think would happen if the
dendrites could no longer receive
signals?
Answer:
I think sorry if wrong ;)
These connections occur at short, root-like tendrils called dendrites, which sprout from the neuron's cell body, or soma. ... As it loses input connections, the wounded neuron also becomes more excitable: the neuron becomes more likely to fire signals down its truncated axon when stimulated to do so by other neurons.
is the mass of wood charcoal and oxygen the same before and after the fire ?
Answer:
Here u go I even looked it up for u ;)
The law of conservation of mass was created in 1789 by a French chemist, Antoine Lavoisier. ... For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant
how are mass and volume alike

A. A spore grows into a mature gamete-producing plant.
B. A zygote forms when a sperm fertilizes an egg cell.
C. A gamete-producing fern plant is flat and shaped like a heart.
D. A mature spore-producing fern plant has fronds and produces
spores.
A zygote forms when a sperm fertilizes an egg cell does stage 4 show. So, the correct option is (B).
What is Zygote?After pollination, the male gametes present in the pollen grains move into the ovules and fuse with the female gametes where the single cell resulting from this fusion is called the zygote. This process is called fertilization.
In flowering plants, a haploid gamete called an egg cell and a sperm cell first fuse to form a diploid cell called a zygote. The zygote is the progenitor stem cell that gives rise to all embryonic and post-embryonic tissues and organs.
Thus, a zygote forms when a sperm fertilizes an egg cell does stage 4 show. So, the correct option is (B).

What are the differences between plants and animals?The main defining characteristics between the organisms of Kingdom Plantae include all the multicellular, photosynthetic eukaryotes category. Plants belong to the kingdom Plantae. Plants are the primary producers of the Earth’s ecosystem. They can prepare their own food (carbohydrates).
The characteristics of the Kingdom Animalia include the organisms which belong to the category of multicellular, eukaryotes. They are classified into various classes such as mammals, amphibians, reptiles, fish, birds, and insects. They cannot prepare their own food. They can move from one location to the other location.

In the given image, it is showing that plants use carbon dioxide gas to make sugars during photosynthesis. The correct option is D.
What is carbon cycle?The carbon cycle is nature's method of recycling carbon atoms, which travel from the ambience into Earth's living organisms and then back into the atmosphere. The majority of carbon is stored in rocks and sediments, with the remainder in the ocean, environment, and living organisms.
Plants consume carbon dioxide and sunshine during photosynthesis to produce fuel i.e., glucose and other sugars for the construction of plant structures. The fast biological carbon cycle is built on this process.
Thus, the correct option is D.

These are called multiallelic traits. If GGHHII was crossed with gghhii, what would the genotype for every offspring be?
a. ggGGhhHHIIii
b. GGhHII
c. GgHhIi
d. ggHHii
Answer:
In the crossing of individuals with multiallelic traits, the crossing of a GGHHII individual with a gghhii individual would produce offspring of hybrid individuals for all three traits whose genotype would be GgHhIi (option c).
Explanation:
The individuals GGHHII and gghhii are pure lines for each of the traits —multiallelic traits— they express, one of them having the three dominant traits and the other three recessive traits. The product of crossing two pure lines with dominant and recessive traits is an offspring of 100% heterozygous individuals.
This can be tested by making a Punnett square for this cross:
GGHHII X gghhii
Alleles GHI GHI
ghi GgHhIi GgHhIi
ghi GgHhIi GgHhIi
Thus the offspring in the cross of two individuals, dominant and recessive, for multiallelic traits G, H and I is GgHhIi

Which of these factors affects how fast a sound wave moves? the kind of material it is moving through the kind of material it is moving through the amplitude of the sound wave's vibrations the amplitude of the sound wave's vibrations the wavelength of the disturbance in the medium the wavelength of the disturbance in the medium the type of motion that caused the sound wave to form the type of motion that caused the sound wave to form
Answer:
the kind of material it is moving through
Explanation:
Sound wave is a type of mechanical wave, which requires a medium to travel, unlike longitudinal waves that can travel through vacuums. Since, sound waves travel through mediums, the KIND OF MEDIUM/MATERIAL it is traveling through has a role to play on how fast it moves.
Sound waves move faster in materials whose molecules are closely packed together than those with loosely packed molecules. This is why sound waves naturally travel faster in SOLID materials. Therefore, the the kind of material the sound wave is moving through affects how fast it moves.
Explain what the greenhouse effect is, use diagrams if you wish.
Include:
-Radiation from the sun absorbs earths heat
-Some emitted
-Trapped by the greenhouse
Answer:
See the answer below
Explanation:
The greenhouse effect refers to the heating effects produced by the earth's atmosphere on the planet as a result of the atmosphere absorbing reflected radiation from the sun by the earth.
The earth's atmosphere is a blanket of gases, some of which are referred to as greenhouse gases. These gases have the capacity to trap radiations coming from the sun that is reflected by the ground layer of the earth. Thus, they produce a warming effect on the earth.
A bulk of the radiation coming from the sun is reflected back into space by the earth's stratosphere. The small percentage that passes through are dispersed in different directions and some of them pass through the atmospheric blanket to reach the ground layer of the earth. While some are absorbed by the ground itself, some are emitted back into the atmosphere where the greenhouse gases trap a large portion and prevent them from escaping back into space.
This leads to the warming of the earth and the entire phenomenon is referred to as the greenhouse effect.

Extant birds and mammals share a number of highly similar characteristics, including but not limited to, enhanced hearing, vocal communication, endothermy, insulation, shivering, respiratory turbinates, high basal metabolism, grinding, sustained activity, four-chambered heart, high blood pressure, and intensive ...
An endotherm is an organism that uses internal body heat to maintain a metabolically suitable temperature rather than relying on ambient heat. The endotherms primarily include the birds and mammals.
Why are birds and mammals endotherm?In contrast to organisms that rely on the heat of their surroundings to sustain a temperature that is optimal for their metabolic processes, endotherms generate their own heat from within their bodies. The majority of endotherms are comprised of different kinds of birds and animals.
Endotherms, which include birds and mammals, generate and store a significant amount of heat within their own tissues, as opposed to ectotherms, which include insects and reptiles, who take in heat from their surroundings. Insects and reptiles are examples of ectotherms.

According to the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, T is not paired with G, hence option C is correct.
What is base-pairing in DNA?Because it is RNA, there is no complementary base pairing between the bases adenine and thymine in DNA. Uracil, which has a structure remarkably similar to that of thymine, is present in place of thymine.
Base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine structure of DNA is created by the binding of these base pairs
Although they keep the two strands of DNA together, they are not strong enough to withstand replication.
