Answer:
dominant traits i believe
Explanation
Answer:
What do you already know about the difference between dominant and recessive traits? Or sex-linked and autosomal traits? Dominant traits are the traits that are normally shown in an organism. Recessive traits are the traits that are not normally shown in an organism overpowered by the dominate trait.
Answer:
4. D (enzymes 1 and 3 works equally well in an acidic and alkaline environment respectively)
5. C. 2; 7; 9.5
Explanation:
The image attached to this question shows a graphical representation of the pH ranges for three enzymes. According to the image;
- Enzyme 1 reached its peak reaction rate at pH 2 (acidic)
- Enzyme 2 reached its peak reaction rate at pH 7 (neutral)
- Enzyme 3 reached its peak reaction rate at pH 9.5 (basic)
This result means that enzymes 1, 2 and 3 will work well and effectively at an acidic, neutral and alkaline environment respectively. Likewise, the optimal pH level for enzymes 1, 2 and 3 are 2; 7; and 9.5 respectively.
<span>Answer: prevent transmission across the synaptic cleft
When the poison binds to the </span>neurotransmitter receptors <span>on the dendrites, it will block the receptors. The neurotransmitter cannot bind to the blocked receptors, making it unable to work. The poison should cause paralyzing effect because the signal cannot be sent.
One of the toxins that work this way is curare.</span>
Metastasis will happen and cancer cells invade nearby healthy cells, tissues, lymph nodes, organs or will migrate to distant organs.
The two different types of stem cells broadly classified as are Embryonic stem cells and adult stem cells. Embryonic stem cells are obtained from the blastocyst layer of the embryo and are pleuripotent. Whereas adult stem cells are the undifferentiated cells from tissues of an adult or a child. They can be unipotent or multipotent.
Explanation:
Cancer cells migrate to other parts of the body via blood and lymphatic system. This is called as metastasis. Cancer cells when becomes tumour they develop their own blood vessels and obtain nutrients from them. Once the tumour gets big it pushes the normal healthy cells of the neighbouring tissues and keeps on spreading.
Stem cells obtained from the embryo can differentiate into any types of cell and when grown in-vitro can dramatically form the three germ layers.
The adult embryo cells are found in less quantity, their role is to repair the tissue they reside in.
