Determine the results from a cross of a mother who is heterozygous for tongue rolling with a father who is homozygous recessive

Biology

grandymaker [24]3 years ago

In order to determine the results from a father who is homozygous recessive for the tongue rolling trait, T, and a mother who is heterozygous for the trait, a Punett square can be used to determine both the resulting genotype (allele combination) and phenotype (observable characteristics). The results are 50% Tt and 50% tt. Thus, the cross would result to 1:1 ratio of tongue rolling to non-tongue rolling offsprings.

Why would a drug that damages capsids help treat a viral infection?
Natasha_Volkova [10]

The correct answer is D. Without capsids, viruses could not replicate

Explanation:

A viral infection is caused as a virus enters the body and this replicates inside it by using the host's cells. This is possible through the capsid which is an external layer in the virus that provides protection to it and helps the virus replicate because the capsid is essential for the virus to attach and penetrate the host's cells to replicate. According to this, if a drug damages the capsids the virus could not replicate and this should or reduce the infection caused by the virus. Thus, a drug that damages capsids helps treat a viral infection because "without capsids, viruses could not replicate".

Elenna [48]
The factor that would least affect photosynthesis is Nitrates in the soil.
Photosynthesis is the process by which plant make their own food by utilizing energy from sunlight, water and carbon dioxide. The limiting factors that affect photosynthesis are the light intensity, carbon dioxide concentration, temperature and water. Without enough light, a plant cannot photosynthesize very quickly, even if there is plenty of water and carbon dioxide.

Aliun [14]

Answer:

Sympathetic nervous system

The sympathetic nervous system of the autonomic division prepares the body for stress or emergency conditions by generating the “fight-or-flight” responses. The sympathetic nervous system triggers the release of stress hormones from the adrenal medulla to generate the set of physiological responses.

There is dilation of the pupil, and an increased rate of heartbeat and increased blood pressure. Other responses include dilation of airways and dilation of blood vessels that supply blood to skeletal muscles, heart muscles, liver, etc. Under the given emergency condition, the sympathetic nervous system of Meghan was activated to generate the fight or flight response.

Question 5: How would you describe the effect of a 1°C increase of temperature on the biodiversity of the
BlackZzzverrR [31]

Explanation:

In the given question, the graph and table have not been provided either they are found anywhere, therefore, the question has been answered on previous knowledge.

The species of Earth can adapt to their environment but adaptation in organisms can take a long time that is thousands to Lakh of years. But the rise in temperature is observed constantly past 200 years.

The species living in the tropics, equator and Poles are already adjusted for their thermal limit. If the average temperature of the planet will increase by 1°C then the number of individuals in the population will decrease. As the number of individuals will decrease, the number of population of species will decrease.

Due to this declination, the number of species can become extinct and therefore the process of increase in temperature and number of species that become extinct can be co-related.
