Answer:
Let's consider that the allele 'B' is for Black hair colour and it is dominant. Let's consider that the allele for red hair colour is b.
Let's consider the allele for lacking horns or polles is 'P' and it is dominant. The allele for having horns is 'p' and it is recessive.
When two heterozygous black, lacking horns (BbPp) are crossed, the results will have the probability of 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned organisms.
Answer:
Like starch, cellulose is a complex carbohydrate made up of many molecules of glucose linked together. But unlike starch, plants do not use cellulose to store energy. Instead, plants use cellulose as a structural molecule. It forms the cell wall that gives plant cells shape and support.
Explanation:
Spirometry (spy-ROM-uh-tree) is a common office test used to assess how well your lungs work by measuring how much air you inhale, how much you exhale and how quickly you exhale. Spirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing
They are called ATPase pump. they pump sodium ions out of the cells and potassium into
Three human activities that may make the slopes unstable are the following:
1. Deforestation
Cutting off trees may result to loose soil since there will be lesser roots that will hold the soil together. When rain water runs off the slope, it will make the slope more unstable, resulting to mud/land slide.
2. Water excavation/extraction
This may also result to unstable slope, because the soil may sink as more water is extracted from the ground to supply the need of the growing population. In extreme cases, this may result to the formation of sinkhole.
3. Drilling of the earth
Drilling may result to unstable slope if is done in a landslide prone area as it will disturb the formation of rocks and soil.
