The pedigree on the right shows the inheritance pattern for an X-linked recessive disorder.
The mother of the individuals circled in pink is not shown on the pedigree. Based on the phenotypes of these individuals and their father, what are the possible genotypes of their mother? Check all of the boxes that apply.
- XAXA
- XaXa
- XAXa
The mother's genotype can be either [tex]X^AX^A[/tex] or [tex]X^AX^a[/tex].
For X-linked recessive traits, males (XY) can either be affected or free from the disorder, they cannot be carriers. Females (XX), on the other hand, can be affected, unaffected, or be carriers.
The circled male child is free from the disorder ([tex]X^AY[/tex]) while the females are carriers ([tex]X^AX^a[/tex]).
The male inherited the healthy allele, [tex]X^A[/tex], from the mother.
The female children inherit the affected allele from their father (who is affected for the disorder) and the other healthy allele from their mother.
This means that the mother cannot be affected for the disease. As it is, the pedigree points that all the children got their healthy alleles from their mother. This does not mean the mother has two healthy alleles though.
Thus, the possible genotype of the mother are [tex]X^AX^A[/tex] and [tex]X^AX^a[/tex].

Describe the steps of a muscle contraction.
(1) A message travels from the nervous system to the muscular system, triggering chemical reactions.
(2) The chemical reactions lead to the muscle fibers reorganizing themselves in a way that shortens the muscle--that’s the contraction.
(3) When the nervous system signal is no longer present, the chemical process reverses, and the muscle fibers rearrange again and the muscle relaxes.

why are different leads are used to measure the ECG
Different leads are used to measure the ECG simply because each lead is recording the electrical activity of the heart from a different direction
Each individual lead's ECG recording is slightly different in shape. This is because when the electrical activity within the heart travels towards a lead you get a positive deflection.
ElectrocardiogramAn electrocardiogram (ECG) is a simple test that can be used to check the heart's rhythm and electrical activity. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats

What are temperate grasslands?Temperate grasslands are biomes characterized by vast expanses of open grasslands with few trees or shrubs. These ecosystems experience a wide range of temperature fluctuations between seasons, with hot summers and cold winters. As a result, animals that live in temperate grasslands have evolved adaptations that enable them to survive in this challenging environment. One of the most common adaptations of grassland animals is the ability to dig burrows. Burrows provide shelter and protection from predators, as well as a stable microclimate for animals to live in.
Hence, structures to dig burrows are a common adaptation for animals that live in temperate grasslands, as is present in the first option.

Explanation:
List the angles in order from smallest to largest. Note image in not drawn to scale
Using sine rule and cosine rule, the angles from smallest to largest is A,B,C.
Using the cosine rule;
a^2 = b^2 + c^2 - 2bc cos A
When;
a = 9 cm
b = 16 cm
c = 18 cm
9^2 = 16^2 + 18^2 - (2 × 16 × 18) cos A
81 = 256 + 324 - (576) cos A
81 = 580 - 576 cos A
81 - 580 = - 576 cos A
cos A = (81 - 580)/ - 576
A = cos-1[(81 - 580)/ - 576]
A = 30°
Using the sine rule;
a/sin A = b/sinB
asinB = bsinA
sinB = bsinA/a
B = sin-1(bsinA/a)
B = sin-1[(16 × sin30)/9]
B = 63°
Now;
A + B + C = 180(Sum of angles in a triangle)
C = 180 - ( A + B)
C = 180 - ( 30 + 63)
C = 87°
The angles are A, B, C.

How does the air pressure at sea level compare with air pressure at higher elevations such as
Mt. Everest. In your explanation include information about the number of air molecules in a
parcel of air at that altitude and the affect of gravity on pressure at both altitudes.
Answer:
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest
tissue respiration, location in the cell and sequence of reaction
Answer:
The Location of Cellular Respiration
Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion.
Tissue respiration occurs internally where the oxygen carried by the blood and RBCs is exchanged with the carbon dioxide produced by the cells of various tissues. ( This answers the location of where tissue respiration occurs
Sequence of tissue respirationThe stages of tissue respiration include:glycolysis - pyruvate oxidation - citric acid or Krebs cycle - oxidative phosphorylation.
Cell tissue respiration
It is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water
Cellular tissue respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate, and then release waste products.

What does it mean for a bacteria or protist to be photosynthetic?
O They are responsible for disease growth.
o They are only responsible for the decomposition of compost.
They are a primary producer of biomass in the ocean.
They are multi-cellular organisms.
If a bacteria or protist is photosynthetic that means they are the primary producer of biomass in the ocean.
What are primary producers?Primary producers are organisms that produce their own food through the process of photosynthesis or chemosynthesis. These organisms are the base of the food chain in most ecosystems, as they provide the energy that drives the ecosystem.
Photosynthetic primary producers, such as plants, algae, and some bacteria, use energy from sunlight to convert carbon dioxide and water into glucose, a type of sugar. They release oxygen as a byproduct of this process.
Chemosynthetic primary producers, such as some types of bacteria, use energy from chemical reactions to convert inorganic substances into organic matter. These reactions typically involve the oxidation of sulfur compounds or methane, and they occur in environments where sunlight is not available, such as deep ocean vents and underground coal mines.
Primary producers are important because they provide the energy that drives the food chain and support the rest of the ecosystem. Without primary producers, higher-level consumers, such as herbivores and carnivores, would not have a source of energy.
