Explanation:
Photosynthesis begins when light strikes Photosystem I pigments and excites their electrons. The energy passes rapidly from molecule to molecule until it reaches a special chlorophyll molecule called P700, so named because it absorbs light in the red region of the spectrum at wavelengths of 700 nanometers.

Hemophilia is an X-linked recessive genetic disorder. A baby girl is found to have inherited the trait from her parents. What are the phenotypes of the parents?
X-linked genes are inherited. The affected girl's father is hemophilic (X-Y), and the mother might be either hemophilic (X-X-) or carrier normal (X+X-).
What are the X-linked genes?
These are the genes located in the X séx chromosome and not in the somatic ones.
Traits coded by these genes are inherited. This is, X-linked genes are transmitted from parents to children through generations.
According to this, X-linked genetic disorder will be inherited as well.
Men have a high probability of being affected since they only have one copy of the X chromosome. In women, the effect of the mutation might be musk in heter0zyg0us state.Hemophilia is a X-linked recessive genetic disorder.
Let us represent the recessive allele with the symbol -, and the dominant allele with the symbol +.
X- is the chromosome carrying the recessive allele X+ is the chromosome carrying the dominant alleleFor the affection to be expressed, the person must be either,
X-X- ⇒ woman/girlX-Y ⇒ man/boyIf the baby girl is found to have inherited the trait from her parents, then her genotype is X-X-. She must have received one X- chromosomes from each parent.
Her father provided the X chromosome, so he must be hemophilic (X-Y)Her mother provided the other X chromosome, but she can be either a carrier (heter0zyg0us, X+X-) or hemophilic (h0m0zyg0us recessive, X-X-).Options,
Cross 1) affected father x carrier mother
Parentals) X-Y x X+X-
Gametes) X- Y X+ X-
Punnett square) X- Y
X+ X+X- X+Y
X- X-X- X-Y
F1) 1/2 = 50% of the progeny is expected to be healthy (25% X+X- girls + 25% X+Y boys)
1/2 = 50% of the progeny is expected to be hemophilic (25% X-X- girls + 25% X-Y boys)
Cross 2) affected father x affected mother
Parentals) X-Y x X-X-
Gametes) X- Y X- X-
Punnett square) X- Y
X- X-X- X-Y
X- X-X- X-Y
F1) 100% of the progeny is expected to be hemophilic (50% X-X- girls + 50% X-Y boys)
the phenotype of the father ⇒ hemophilic (X-Y)the phenotype of the mother ⇒ normal carrier (X+X-) or hemophilic (X-X-)You can learn more about séx-linked genes at

During which phase of meiosis do the homologous chromosomes line up across from each other in the center of the cell?
Answer: In metaphase I, homologous chromosomes line up along the center of the cell in order to be pulled apart.
Explanation:
Meiosis is the type of cell division in the germinal cells. In metaphase I of meiosis, the homologous chromosomes line up across from each other in the center of the cell.
What is metaphase I?Metaphase I is one of the stages of meiosis I in which the duplicated homologous chromosome pairs align at the center of the cell along the midline and are connected through the centrioles.
In prophase I the homologous chromosomes are created and in anaphase I, the aligned chromosomes move towards the opposite poles so that after division each cell has the same number and equal composition of chromosomes.
Therefore, in metaphase I the homologous chromosomes are aligned at the midline.

What is a trophic level?
A. the amount of energy that an organism uses to survive in an ecosystem
B. all of the nonliving things in an ecosystem
C. a model used to show the types of organisms in an ecosystem
D. a living organism's position in the flow of energy through an ecosystem
Answer:
D. A living organisms position in the flow of energy through an ecosystem.
Explanation:
Its like each step up in the food web/pyramid.
Trophic level is a living organism's position in the flow of energy through an ecosystem. The correct option is D.
A biological organism's place or function in the movement of energy through an ecosystem is referred to as its trophic level. It symbolises the ecological community's hierarchy of feeding.
A trophic level's inhabitants have comparable feeding habits and occupy a certain place in the food chain.
The first trophic level is occupied by the primary producers, including plants and algae, which use photosynthesis to transform sunlight into energy.
The second trophic level is occupied by herbivores that consume producers directly, followed by primary carnivores (predators that consume herbivores) on the third level, and so forth.
A complex network of energy flow and nutrient cycling occurs within an ecosystem at each trophic level as creatures consume and are consumed by one another.
Thus, the correct option is D.
