Answer:
Inheritance patterns differ for genes on sex chromosomes (chromosomes X and Y) compared to genes located on autosomes, non-sex chromosomes (chromosomes numbers 1-22). This is due to the fact that, in general, females carry two X chromosomes (XX), while males carry one X and one Y chromosome (XY).

4. Many commercial grow lights deliver light mostly in the yellow/red part of the spectrum, along with smaller portions of all other visible light. Why would a grow light such as this promote plant growth and reproduction (flowering and fruiting) or is this a con job?
Answer and Explanation:
These lights can, in fact, promote the growth and reproduction of plants.
This is because growth, chlorophyll production, flowering and fruiting only occur if the plant is exposed to a band of light with 640-720 nm. Plants receive this band of light naturally through the sun, but when solar energy is not available it is possible to use cultivation lamps that emit this type of light band, which corresponds to the yellow/red spectra.
What are the organelles that a plant cell has that is different than the animal cell? Explain each one

Answer:
B)
Explanation:
"Positive feedback encourages and intensifies a change in the body's physiological condition, driving it farther out if the normal range."
Sickle cell anaemia is an inherited autosomal recessive
condition caused by a mutation in the haemoglobin
subunit beta (HBB) gene. A male and female who are
phenotypically normal, discover through genetic testing
that they are both carriers of a HBB mutant allele. What is
the probability that their first child will be biologically
female and phenotypically normal?
Answer:
1/8 (12.5%)
Explanation:
An autosomal recessive disease is an inherited disease in which an individual need to receive both defective alleles at the same gene locus to be expressed in the phenotype. In this case, both parents are carriers of the recessive mutant allele associated with the sickle cell anaemia trait, thereby both parents are heterozygous, ie., each parent has one copy of the normal allele 'H' and one copy of the defective mutant allele 'h' associated with this condition. In consequence, their first child has a 1/4 (25%) chance of having sickle-cell anaemia. Moreover, the chance of having a girl is 1/2 and the chance of having a boy is 1/2, thereby the final chance of having a girl sickle cell anaemia individual is 1/4 x 1/2 = 1/8 (12.5%).
- Parental cross for sickle cell anaemia trait = Hh x Hh >>
- F1 = 1/4 HH (normal); 1/2 Hh (normal); 1/4 hh (sickle cell anaemia) >>
- Sex proportion of sickle cell anaemia individuals = 1/8 female sickle cell anaemia individuals + 1/8 male sickle cell anaemia individuals (1/8 + 1/8 = 1/4)

The organs found in plants or animals is stem vascular. Therefore, option (D) is correct.
What are the features of the stem vascular?A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients.
The vascular system of plants, complete with xylem and phloem, fills both purposes. Stems, along with roots, also store food for the plant. Pith, a tissue that lies in the center of the stem.
A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in the stem, which exists in two forms: xylem and phloem.

Which of the following would be an accurate food chain that could be found in the
tropical community?
A) cougar --> turtle --> banana
B) insect --> frog --> ocelot --> parrot
C) fruit --> turtle --> cougar
D) vegetable --> insect --> mushroom
Answer: B
Explanation:
The animals that live in tropical areas are in option B. Cougars can not live in the tropics, they live in the cold biomes. In the tropics, there are many insects, and frogs eat them. Ocelots eat the frogs, and the ocelots are eaten by parrots. The rest of the options are valid food chains, but they would not function in the area of tropics. The answer to the question is option B.
Acid precipitation may change lakes by a. making phosphorus more available to plants, thereby increasing productivity. b. making nitrogen more available to plants, thereby increasing productivity. increasing populations of nitrogen-fixing microorganisms. . accelerating the carbon cycle within lakes. causing the local extinction of species that cannot tolerate
Answer:
causing the local extinction of species that cannot tolerate.
Explanation:
Acid precipitation may change lakes by causing the extinction of local species that cannot tolerate the acidity of the water. The acid precipitation damaged the skin of the aquatic organism as well as internal body structure of various organisms. Acidic nature of water is not good for all organisms except some resistance organisms due to their adaptability so we can conclude that extinction of species occur that has no resistance.
