In x linked recessive if the mother is carrier and father is normal and their first child is male and is affected the next child

is female, how much chances are there that she will be carrier?
Biology

Phantasy [73]3 years ago
6 0

Answer:

A 50% chance I believe. The mother will always give the X chromosome and since the father is normal and doesn't carry that ressecive trait they can only get it from the mother. (I'm not completely sure!))

Using a microscope, Quinlin notices a small green organelle inside a cell. Which of the following is most likely to occur first
jek_recluse [69]

Answer:

D.The light-dependent reactions absorb sunlight and transfer the energy to electrons.

Explanation:

Firstly, the organelle that was described as small green organelle inside a cell as noticed by Quinlin is the CHLOROPLAST. Chloroplast is an organelle present in the cells of green plants, in fact, it makes plants green. Chloroplast is the organelle where the unique process of PHOTOSYNTHESIS occurs in plant cells.

However, the photosynthetic process is divided into stages namely: light-dependent and light-independent stages. The light dependent stage, which involves the production of ATP (energy carrier) and NADPH (electron carrier), must PRECEDE the light independent stage or Calvin cycle. Chloroplast contains a pigment called CHLOROPHYLL, which absorbs light energy from the SUN in order to power the light dependent stage of photosynthesis.

Hence, the light-dependent reactions, which absorb sunlight and transfer the energy to electrons must occur first in the organelle.

What unusual property do cytochromes have in common with hemoglobin or myoglobin?
Ghella [55]
The unusual property that cytochromes have in common with hemoglobin or myoglobin is that all of them contain heme groups. Cytochromes are heme-containing electron transport enzymes which are essential for the oxidative metabolism necessary to generate adenosine triphosphateas well as for the oxidative degradation of drugs and endogenous substrates.

Indicate whether each statement is true or false: 1. Compliance is the tendency for blood vessel volume to increase as blood pre
Evgesh-ka [11]

Answer:

1. False

2. False

3. True

Explanation:

1. Compliance is the capacity of a container to increase in size to allow it hold more content. Blood vessel, arteries and veins expand (increase in volume) to be able to accommodate a surge in blood flow, which is as a result of an increase in pressure of the blood from the heart pumping of the blood

Therefore, compliance in the tendency for blood vessel volume to increase as the blood pressure <em>increases</em> not decrease

The statement is false

2. A large compliance is indicative of being highly sensitive to changes in pressure

Compliance, C = ΔV/ΔP

From the above equation, a blood vessel with a large compliance, exhibit a large increase in volume when the increase in pressure is small

Therefore, the statement 'Blood vessels with a large compliance exhibit a small increase in volume when pressure increases a small amount; is false

3. The compliance of the vein ranges from 10 to 20 times (30 times in some literature) greater than arteries. A factor which can be affected by the vascular smooth muscle contraction or relaxation

Therefore, the statement, 'venous compliance is approximately 24 times larger than arterial compliance, so as venous pressure increases the volume of veins greatly increases' is true

List and describe the three elements of media literacy
mariarad [96]

The first stage is simply becoming aware of the importance of managing one's media "diet"--- that is, making choices and reducing the time spent with television, videos, electronic games, films and various print media forms.

<span>The second stage is learning specific skills of critical viewing--- learning to analyze and question what is in the frame, how it is constructed and what may have been left out. Skills of critical viewing are best learned through inquiry-based classes or interactive group activities, as well as from creating and producing one's own media messages.
</span>

The third stage goes behind the frame to explore deeper issues. Who produces the media we experience and for what purpose? Who profits? Who loses? And who decides? This stage of social, political and economic analysis looks at how everyone in society makes meaning from our media experiences, and how the mass media drive our global consumer economy. This inquiry can sometimes set the stage for various media advocacy efforts to challenge or redress public policies or corporate practices.
