Ribosomes are organelles that are responsible for creating proteins by assembling amino acids based on the information provided by messenger RNA (mRNA). They can be found in both prokaryotic and eukaryotic cells. The Golgi Apparatus is a stacked organelle that modifies, sorts, and packages proteins into vesicles for transport to their final destinations within the cell or for secretion outside the cell.
Microtubules are part of the cytoskeleton, which is a network of protein fibers that provide structural support and shape to the cell. Microtubules are responsible for moving proteins and other cellular components to the correct regions of the cell, and they also play a role in cell division. The cytoskeleton is the network of protein fibers that provide structural support and shape to the cell. It is responsible for fortifying the cell shape and helping the cell maintain its structural integrity.
The cytosol is the liquid portion of the cytoplasm, which is the gel-like substance that fills the cell. It is mostly made of water and contains various dissolved ions, molecules, and proteins that are essential for cellular processes.

What powers the carbon cycle?
Answers
Answer:
\( \: \)
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
Answer:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to make Earth capable of sustaining life. It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks. Carbon sinks in the land and the ocean each currently take up about one-quarter of anthropogenic carbon emissions each year.

The flowchart below is a model of how a stimulus in an animal's environment can result in a change in the animal's behavior. Use the labels provided to complete the model.
Answers
1) environmental stimulus 2) sensory receptors 3) brain 4) memory 5) behaviour.
Explain how a stimulus in an animal's environment can result in a change in the animal's behavior?(1) Environmental stimulus: A stimulus is any detectable change in an animal's environment that can potentially affect the animal's behavior. For example, a loud noise or the presence of food can be stimuli.
(2) Sensory receptors: When a stimulus is detected by an animal's sensory receptors (such as eyes, ears, nose, or skin), it sends signals to the animal's brain via sensory neurons.
(3) Brain: The animal's brain receives and processes the signals from the sensory receptors, which can result in the activation of specific neural circuits and the release of various neurotransmitters.
(4) Memory: Depending on the animal's past experiences, the stimulus may trigger certain memories and associations that influence the animal's behavior. For instance, if the animal has learned to associate a particular sound with danger, it may respond differently than if it had no prior experience with that sound.
(5) Behavior: Finally, the combined effects of the sensory input, brain processing, and memory can result in a change in the animal's behavior. The animal may move towards or away from the stimulus, vocalize, exhibit a particular social behavior, or engage in any other response that is appropriate for the situation.

A.
amoeba
B.
archaea
C.
dinoflagellates
D.
algae
E.
euglenoids
Answers
Explanation:
The organisms found in the subtropical forests of southern China which were acid tolerant and lacked internal organelles are the Archaea. Archaea refers to the domain of life with organisms living in extreme conditions. Because of this, the Archaea are referred to as the extremophiles.
The cells are very small, prokaryotic and are similar to bacteria in lacking a nucleus and membrane bound organelles. The cell membrane is bounded by a cell wall. They reproduce by binary fission, fragmentation or budding.
They can tolerate high temperatures and survive in hot springs, anaerobic conditions and are acid-tolerant. These acid tolearting Archaea are called the acidophiles surviving in a pH of 2 or less than 2.
They pump out protons out of the intracellular space and thus keep their cytoplasm in a neutral pH or have an acidified cytoplasm. The example are Thiobacillus acidophilus, Crenarchaeota and others.

There are three different phenotypes corresponding to genotypes S^AS^A S^AS^B and S^BS^B respectively in a flock of 175 sheep the frequency of allele S^A was found to be 0.6 and frequency of allele S^B WAS found to be 0.4
Answers
Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.
What is Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.
Assuming a diallelic gene,
Allelic frequencies
The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is qGenotypic frequencies
p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example,
Alleles Frequencies
S^A f(S^A) = p = 0.6S^B f(S^B) = p = 0.4Genotypes
S^AS^A ⇒ homozygousS^AS^B ⇒ heterozygousS^BS^B ⇒ homozygousWe need to get the number of animals expressing each genotype and phenotype. To do it, we just need to use allelic frequencies and calculate genotypic frequencies (p², 2pq, and q²), and then multiply these values by the total number of animals (N = 175).
Genotypic and Phenotypic frequencies
F(S^AS^A) = p² = 0.6² = 0.36
F(S^AS^B) = 2pq = 2 x 0.6 x 0.4 = 0.48
F(S^BS^B) = q² = 0.4² = 0.16
Number of individuals expressing each phenotype
S^AS^A ⇒ 0.36 x 175 = 63 individualsS^AS^B ⇒ 0.48 x 175 = 84 individualsS^BS^B ⇒ 0.16 x 175 = 28 individualsYou can learn more about the Hardy-Weinberg equilibrium at

Explanation:
A group of researchers transformed E. coli to express
dsRNA that matched a transcription factor, eaf-1. They
then fed these E. coli to C. elegans worms. When the
researchers examined the C. elegans, they found that
they had fewer offspring and were smaller individuals,
with similar characteristics to C. elegans in which eaf-1
had been knocked out.
The students suggested several hypotheses based on
these observations about how RNAi worked:
1. The dsRNA inhibited gene transcription.
2. The dsRNA inhibited mRNA processing.
3. The dsRNA inhibited translation of mRNA into protein.
4. The dsRNA inhibited protein folding.
Mark this and return
The researchers then performed a series of experiments
to determine which hypothesis was correct. The C.
elegans were found to be transcribing eaf-1 into mRNA,
but not producing eaf-1 protein. When the students
directly injected C. elegans with dsRNA and tracked
tagged mRNA, they found the mature mRNA was
degraded in the cytoplasm, and ribosomes were not
binding to it. Which hypothesis is supported by these
observations?
Answers
The hypothesis that is supported by these observations is that the dsRNA inhibited the translation of mRNA into protein (third option).
What does the experiment reveal about dsRNA?In this experiment, the C. elegans worms were transcribing eaf-1 into mRNA but not producing the eaf-1 protein. This phenomenon shows that dsRNA inhibited the translation of mRNA into protein related to the action of E. coli on the worms.
This also explains why the worms affected by this bacteria had fewer offspring and the offspring were smaller.

How are incomplete dominance and codominance different than a normal Mendelian cross?A. There is no differenceB. The heterozygous genotype has a unique phenotypeC. There is no heterozygous phenotypeD. There is only one phenotype regardless of genotype
Answers
In Mendelian cross, codominance and incomplete dominance the heterozygous will always have a unique phenotype. As they don't differ in this matter, B is incorrect.
There is a heterozygous phenotype and it is different than a homozygous recessive or a homozygous dominant, and it applies to Mendelian cross, to codominance and to incomplete dominance as well. Therefore, C and D are also incorrect.
The Mendelian laws of inheritance does not identify codominance or incomplete dominance, but it can lead to their identification as they do not differ in its function. Therefore, the correct answer is A. There is no difference.

Answer:
YES, DEFINITELY.
Explanation:
An ecosystem is a community or group of organisms that live and interact with each other in a particular environment. Especially in the context of agroecosystems, it is often better to think of insects as populations rather than individuals. Knowing the age distribution of pest populations can indicate the potential for crop damage. For example, when most streaky cucumber beetles are immature, they do little direct damage to the above-ground parts of the plant.
