Answer:
It activates Cdc25, which in turn activates more M-Cdk
Explanation:
Cyclin are enzymes that regulate cell cycle progression by the activation of cyclin-dependent kinases (CDKs). These cyclins have no enzymatic activity on their own but they can activate Cdks by binding and phosphorylating them. CDKs can be activated by phosphorylation of activating sites and/or dephosphorylation of inactivation sites. Moreover, M-phase cyclins are cyclins that form M-CDK complexes in order to modulate the cell's entry into mitosis. Cdc25 is a phosphatase involved in the eukaryotic cell cycle which is well-known to regulate the entry into and progression during S (DNA Synthesis) phase and mitosis. In this regard, it has been shown that mitotic phosphorylation of Cdc25 by M-Cdks increases its intrinsic phosphatase activity, thereby Cdc25 is able to remove inhibitory phosphates from M-Cdk and, consequently, activate more M-Cdks.

Answer:
1. Alveoli: tiny air sacs within the lungs.
2. Bronchi: the two tubes into which the trachea divides before entering the lung.
3. Diaphragm: a muscle below the lungs used for breathing.
Explanation:
Living system can be defined as the internal systems of organisms and how materials circulate within organisms.
Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.
Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc., which are typically used for carrying out various bodily functions such as respiration, metabolism, digestion, etc.
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
1. Alveoli: it comprises tiny air sacs and it's located within the lungs of living organisms.
2. Bronchi: these are the two (2) tubes into which the trachea divides (the right bronchus and the left bronchus) before entering the lung.
3. Diaphragm: it's a muscle located below the lungs and typically used for breathing in all living organisms.

Why making anti-viral medicines is harder than making anti-bacterial medicines ?
Also Is Virus a living parasites?
Answer:
Making anti-viral drugs is more difficult than making anti-bacterial medicines because viruses have very few biochemical mechanisms of their own. They make use of host machinery which replicates. So it is very much difficult to find the targets where these drugs get interfered by not making any harm to the host. Thus, it is not easy to design an antiviral drug with high safety and effectiveness.
Explanation:
And i would say virus is a parasites but not a living parasite according to md
Answer:
Because antivirals can damage host cells where the viruses reside.
I hope this helps
all viruses are obligate parasites,that is they lack metabolic machinery of their own to generate energy or to synthesize proteins,so they depend on host cells to carry out these vital functions...
Bacteria species live in the intestinal tracts of many types of mammals. These bacteria consume the partially digested food the mammal eats but also help to complete digestion of the food for mammals. This represents a ________________ relationship between species.
A) Predation
B) Mutualistic
C) Competitive
D) Commensalism
Answer:
B) Mutualistic
Explanation:
A mutualistic relationship is one of the symbiotic relationships that involves two organisms whose actions benefit one another. In mutualism both parties interact with one another and gain from one another.
According to this question, a bacteria species live in the intestinal tracts of many types of mammals. The bacteria helps the mammal to completely digest the food while the mammal provides shelter and food for the bacteria. This represents an example of MUTUALISTIC RELATIONSHIP.

What adaptations did Charles Darwin notice in the finches of the Galapagos Islands that helped him develop his theory of evolution by natural selection?
A. All of the finches looked the same regardless of the island from which they came.
B. The finches had the same beak sizes and shapes as the mainland finches.
C. The finches had gone extinct from the islands due to volcanic activity.
D. The finches had beaks of different sizes and shapes that were suited to the available food.
Answer:
the answer is D
Explanation:
hope this helps:)
Charles Darwin noticed that the finches had beaks of different sizes and shapes that were suited to the available food. Option D is correct.
Changes in their beak size and shape have allowed them to adapt to different food sources: seed, insect, cactus flower and fruit, or even bird’s blood. Adaptive radiation is a well-known feature of the Galapagos finches.
Darwin concluded that these differences allowed the finches to better adapt to the food in their specific habitat - thin sharp beaks where the birds feed on insects and grubs and large claw-like beaks where they feed on buds, fruits, and nuts.
So the correct option is D.

In meiosis, sister kinetochores are attached to the same pole of the cell during meiosis I, and sister chromatid cohesion is released during anaphase II. What would be the likely result if sister kinetochores were attached to different poles of the cell during meiosis I and sister chromatid cohesion was released during anaphase I
Answer:
sister chromatids would migrate to opposite poles in anaphase I
Explanation:
Kinetochores are multiprotein structures that establish the attachment of spindle microtubules to the chromatids during cell division (either mitosis or meiosis). Sister chromatid cohesion at the centromeres refers to the mechanism by which sister chromatids are paired and held together during meiosis I. This process (sister chromatid cohesion) is fundamental to ensure the correct orientation of chromatids on the spindle microtubules and their subsequent segregation in meiosis II. The fusion of sister kinetochores in meiosis I underlies sister chromatid cohesion during this stage of the cell division, thereby their disruption or destruction of sister chromatid cohesion would lead to separation and segregation of sister chromatids to opposite poles of the cell in anaphase I.

WHAT IS PHOTOSYNTHESIS ??
[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]
What's photosynthesis?[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Photosynthesis is the process in which green plants derive their food (nutrients and water) through the capturing of light energy (sunlight) and using it to convert carbon dioxide (CO2) and water (H2O) into oxygen (O2) and other substances (compounds) that are rich in energy. Chlorophyll a green pigment present in plants is used in this process.

The founder effect occurs when Multiple Choice large groups of individuals leave their home population and establish new settlements, mating only among themselves. small groups of individuals leave their home population and establish new settlements, mating only among themselves. many members of a population die, resulting in a great loss of genetic diversity. many members of a population reproduce causing too much genetic diversity within the population. small groups of individuals leave their home population and join established settlements, and mating with natives.
Answer: small groups of individuals leave their home population and establish new settlements, mating only among themselves.
Explanation:
The founder effect is what happens when a small group of individuals leave their home population in order to establish new settlements. They will then mate only amongst themselves and colonize the area without mixing with the natives.
As a result of the founder effect, there is less genetic variation in the new population than in the home one because the smaller number of individuals who left would not possibly be able to carry all the genes in the home population. The only genes that would be passed on are those of the small individuals.

define the term excretion.
state an excretory product that is passed out trough the lungs.
outline the role of the liver in excretion.
Answer:
Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin.
Carbon dioxide
The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.
