Answer:
All alleles on the X chromosome are dominant
Explanation:
This is because the X chromosome is large and contains many more genes than the smaller Y chromosome. In a sex-linked disease, it is usually males who are affected because they have a single copy of X chromosome that carries the mutation.

cycle?
A. RNA DNA → RNA protein
B. protein
- DNA - RNA → DNA
C. DNA - RNA DNA protein
D. RNA - protein - RNA - DNA
Answers
HIV is a retrovirus whose sequence is RNA DNA → RNA protein which it uses as part of its reproductive cycle. So, the correct option is A.
What is HIV?HIV stands for Human Immunodeficiency Virus which is defined as a virus that attacks the body's immune system. If HIV is not treated, it can lead to AIDS which stands for acquired immunodeficiency syndrome. There is currently no effective cure, while once people have HIV, it remains with it for life.
HIV can spread through sexual contact, illicit injection drug use or sharing needles, contact with infected blood, or from mother to child during pregnancy, childbirth or breastfeeding. HIV is a retrovirus whose sequence is RNA DNA → RNA protein which it uses as part of its reproductive cycle.
So, the correct option is A.

If a population pyramid has a very broad base then what does that tell you about the population it represents?
Answers
Answer:
A population pyramid is defined as a graphical representation that shows distribution of both genders male and female in all age groups.
The base of a population pyramid represents the birth rate, so a very broad base represents the higher population of younger age children and higher birth rate.
Hence, the wide base shows higher population of younger age children and higher birth rate.
Transpiration is the evaporation of water from the surface of a plant. Explain.
Answers
Answer:
Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapor. Of all the water absorbed by plants, less than 5% remains in the plant for growth.

Answers
Answer:
D. pigments; starch.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
A chromoplast can be defined as a heterogeneous organelle or plastids that is typically responsible for pigment synthesis and their storage in a plant. The pigments include red, orange, yellow or chlorophyll.
On the other hand, leucoplast is a colorless plastid i.e plastic lacking photosynthetic pigments that are typically found in storage organs, underground stems, cotelydons, roots, tubers, seeds, or endosperm etc., used for the storage of starch in the absence of sunlight.
Hence, a chromoplast stores pigments while a leucoplast stores starch.

Explanation:
what caused a decrease of carbon dioxide in the biodomes air
Answers
Answer:
As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. ... Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall.
There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease like photosynthesis, respiration, ventilation and carbon sequestration.
What are the factors responsible for decrease of carbon dioxide in the biodomes air?There are several possible reasons why the carbon dioxide levels in the air of a biodome might decrease. Some possible causes include:
Photosynthesis: If the biodome contains plants, they may be using carbon dioxide during photosynthesis to produce oxygen and glucose. This process would remove carbon dioxide from the air.
Respiration: If the biodome contains animals or microorganisms that respire, they may be consuming oxygen and producing carbon dioxide. This would result in a decrease in carbon dioxide levels in the air.
Ventilation: If the biodome has a ventilation system, it may be designed to remove excess carbon dioxide from the air. This could result in a decrease in carbon dioxide levels.
Carbon sequestration: If the biodome has systems in place to capture and store carbon dioxide, such as through the use of plants or other methods, this could result in a decrease in carbon dioxide levels in the air.
It's important to note that the specific cause of a decrease in carbon dioxide levels in the biodome's air will depend on the specific conditions and systems in place within the biodome.

Cell membrane
Explanation:
describe the structure and functions of various organelles in a mature animal cell
Answers
Answer:
Explanation:
Cell Membrane
A thin semipermeable membrane layer of protein and fats surrounding the cell. Its primary role is to protect the cell from its surrounding. Also, it controls the entry and exit of nutrients and other microscopic entities into the cell.
Nuclear Membrane
It is a double-membrane structure that surrounds the nucleus. It is also referred to as the nuclear envelope.
Nucleus
It is an organelle that contains several other sub-organelles such as nucleolus, nucleosomes and chromatins. It also contains DNA and other genetic materials.
Centrosome
It is a small organelle found near to the nucleus which has a thick centre with radiating tubules. The centrosomes are where microtubules are produced.
Lysosome (Cell Vesicles)
They are round organelles surrounded by a membrane and comprising digestive enzymes which help in digestion, excretion and in the cell renewal process.
Cytoplasm
A jelly-like material which contains all the cell organelles, enclosed within the cell membrane. The substance found within the cell nucleus, contained by the nuclear membrane is called the nucleoplasm.
Golgi Apparatus
A flat, smooth layered, sac-like organelle which is located near the nucleus and involved in manufacturing, storing, packing and transporting the particles throughout the cell.
