Plasmodium, the world’s most lethal parasite, causes malaria. The parasite enters thebloodstream through a mosquito bite, hiding in the human liver before invading red blood
cells. Ultimately, millions of infected blood cells explode at once, causing fever and death
in 3 million people a year worldwide.

-- State one reason why Plasmodium is considered a parasite of humans. [1]
-- State one negative impact on humans when the use of pesticides for mosquitoes is decreased. [1]
-- If a large quantity of herbicide, a chemical that is designed to kill weeds, were accidentally spilled into
a large lake, it could endanger all the organisms living in the lake. State one way the effects of killing
the weeds in the lake could be destructive to populations of fish and other animals.

Answers

Answer 1
Answer: it is a parasite for humans because it remains dormant in the carrier organism which in this case is the mosquito.
When the pesticides use for mosquito is decreased,the mosquito population increases which exposes the human population to the risk of being infected by plasmodium.
herbicides are the chemicals that are designed to kill the unwanted herbs. these chemicals contain harmful elements that can cause the other aquatic life to die as well. one effect of the herbicide is that it deprives the water of oxygen which is essential for the fish and other animals living the lake.

You decide to put $150 in a savings account to save for a $3,000 down payment on a new car. If the account has an interest rate of 2.5% per year and is compounded monthly, how long does it take you to earn $3,000 without depositing any additional funds? A. 10.1101 years
B. 119.954 years
C. 121.321 years
D. 134.34 years

Answers

Principal amount deposited in a savings account = $150
Final amount of money needed = $3000
Percentage of interest = 2.5%
Let us assume the time taken = t years
Then
A = P (1 + r/n) ^ nt
3000 = 150(1 +0.025/12)^t
3000 = 150 * (1 + 0.002083)^t
(1.002083)^t = 20
Taking log on both sides we get
log (1.002083)^t = log 20
t * ln(1.002083) = ln(20) 
t = ln(20)/ln(1.002083)
  = 1439.68
  = 119.973 years
From the above deduction we can easily conclude that the correct option among all the options that are given in the question is the second option or option "B".

which of the following is not one of the four nitrogenous bases found in DNA ? A: Adenine B: Guanine C: Uracil D: cytosine

Answers

Answer:

Adenine.

Explanation:

Final answer:

In the list provided, uracil (U) is not a nitrogenous base found in DNA. It is instead found in RNA. The DNA bases are adenine, guanine, cytosine, and thymine.

Explanation:

The nitrogenous bases found in DNA are adenine (A), guanine (G), cytosine (C), and thymine (T). In this case, uracil (U) is not one of these four bases. Uracil is a nitrogenous base, but it is not found in DNA; instead, it is present in RNA, another vital nucleic acid in the body that works in conjunction with DNA to produce proteins. The base pairs in DNA are A-T (adenine - thymine) and G-C (guanine - cytosine), while in RNA, the base pairs are A-U (adenine - uracil) and G-C (guanine - cytosine).

What other autoimmune diseases is pernicious anemia associated with?

Answers

Pernicious anemia is an autoimmune disease that primarily affects the absorption of vitamin B12 in the stomach. While pernicious anemia itself is not directly associated with other autoimmune diseases, individuals with autoimmune conditions may have an increased risk of developing multiple autoimmune diseases simultaneously.

Some autoimmune diseases that individuals with pernicious anemia might be at a higher risk of developing as part of APS or due to shared autoimmune mechanisms include:

Autoimmune Thyroid Diseases:

These include conditions like Hashimoto's thyroiditis and Graves' disease.

Type 1 Diabetes:

An autoimmune form of diabetes.

Addison's Disease:

An autoimmune condition affecting the adrenal glands.

Vitiligo:

An autoimmune disorder causing depigmentation of the skin.

Celiac Disease:

An autoimmune disorder triggered by the ingestion of gluten.

Rheumatoid Arthritis:

An autoimmune disease that primarily affects the joints.
