Answer:
a. 50%
Explanation:
<em>BRCA1 genes is a tumor supressor gene whose harmful mutation can cause hereditary breast ovarian cancer syndrome in both males and females. The BRCA actually stands for breast cancer.</em>
<em>Mutation in BRCA1 gene is heritable and every progeny of a carrier parent irrespective of the sex has a 50% chance of inheriting the trait from such parent, be it from the mother or the father.</em>
Hence, the correct option is a.
When ten or more pre-synaptic neurons conduct impulses to five or fewer post-synaptic neurons, the conduction pattern is said to be <u>convergent</u>.
A neuron in such a network can take information from numerous other neurons through convergence. Inhibitory interneurons are activated by presynaptic cells, but instead they reduce nearby cells inside the network.
Synaptic divergence refers to the dispersion of synapses from such a single neuron onto several postsynaptic partners as well as partner kinds, while synaptic convergence refers to being affected by having neuronal cell kinds delivering input around on a shared postsynaptic partner.
Multiple presynaptic cells send convergent information to a single postsynaptic neuron.

The answer to this question would be: 14%
Protein will give a calorie about 4kcal/gram. Then, the total calorie of protein from Susan meal would be: 70 grams * 4kcal/g= 280 <span>kilo calorie</span>.
To find the percentage you will need to divide the total calorie diet with the protein calorie. The calculation would be:
protein percentage= protein calorie/ total calorie
protein percentage= 280kcal / 2,000kcal = 14%
Answer:

Answer:
The correct answer is option - A. 0.
Explanation:
Producers are the organism that produces on their own. They do not depend on other organisms for their nutrition and energy such as green plants. They transfer energy and nutrition.
In the given scenario there is no producer present all are consumers of different levels. Cricket is a primary consumer, a spider is a secondary consumer and bird is the third consumer in this food chain.
Thus, the correct answer is option- A. 0.
