Answer:
the number after 1:the process of photosynthesis is energy realising because the process converts light energy into free into free energy that can be used for cell functions
Explanation:
in has some explanations about photosynthesis
Answer:
D
Explanation:
Absolute age is defined as the numeric age of fossils.
To identify the absolute age of a fossil, the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.
Hence, the correct answer is "D".
Answer:
The correct order is
Prophase l , Metaphase l, Anaphase I, Telophase l, Prophase ll, Metaphase II, Telophase ll / Cytokinesis ll
Explanation:
In Meiosis there are total two phases - Meiosis I and Meiosis II and each phase consists of total six sub phases which are as follows -
Meiosis I
1. Prophase I
2. Prometaphase I
3. Metaphase I
4. Anaphase I
5. Telophase I
6. Cytokinesis I
Meiosis II
1. Prophase II
2. Prometaphase II
3. Metaphase II
4. Anaphase II
5. Telophase II
6. Cytokinesis II
Hence the correct order is
Prophase l , Metaphase l, Anaphase I, Telophase l, Prophase ll, Metaphase II, Telophase ll / Cytokinesis ll
Answer:
d) diploidy
Explanation:
PKU is a genetic condition caused by changes in genes and are transferred through generations in a recessive inheritance pattern. PKU is caused by mutations in the gene PAH phenylalanine hydroxylase (PAH) which codes for an enzyme (type of protein) called phenylalanine hydroxylase. PKU is caused by an Autosomal recessive pattern i.e A person must have a mutation on BOTH of his/her two copies of the PAH gene in order to have PKU and this only occurs if both parents are carriers for PKU.
Now , What maintains the presence of this harmful allele(The recessive allele that causes phenylketonuria (PKU)) in a population's gene pool?
NOTE the word recessive!
The answer is Diploidy.
This is because, the term diploidy refers to a state of having two sets of the chromosomes (and therefore two copies of genes), especially in somatic cells. Therefore, the usefulness of this is to stabilize the chromosome if one of the chromosome(i.e one copy of the gene) is a carrier of PKU.
Answer:
In statistics, a population is the entire pool from which a statistical sample is drawn. A population may refer to an entire group of people, objects, events, hospital visits, or measurements. A population can thus be said to be an aggregate observation of subjects grouped together by a common feature.
