Answers

Answer:

Considering the whole progeny ⇒ the probability of having a girl heterozygous for both genes is 4/16 = 1/4 Considering only girls ⇒ the probability of having a girl heterozygous for both genes is 4/8 = 1/2Considering only dwarf girls with normal color vision ⇒ the probability of having a girl heterozygous for both genes is 4/4 = 1

¿Cómo defines a una Célula Haploide?

Answers

Answer:

La mitad de cromosomas.

Explicación:

Las células haploides se refieren a aquellas células que tienen la mitad de cromosomas. Estas células haploides se forman debido a la división celular de la meiosis. En la división celular de la meiosis, una célula madre se divide en cuatro células hijas que tienen la mitad de cromosomas. Estas células haploides están presentes en los espermatozoides de los gametos masculinos y femeninos, que se fusionaron formando células diploides que tienen el doble de cromosomas. El cigoto formado debido a la fusión de espermatozoides y óvulos son de naturaleza diploide.

Scientists in Brazil have developed specific fertilizers and special breeds of soybeans and corn so crops can grow on large areas of tropical lands. This is valuable because farmers can help to feed the growing human population and strengthen the economy. However, trade-offs must be considered because farming on tropical lands can also A add helpful microorganisms to the soil B remove oxygen from the atmosphere C reduce populations of native species D reduce mutations and disease in wildlife populations

Answers

Answer:

C reduce populations of native species

Explanation:

The overexploitation of the land by farming practices represents one of the most important challenges that face wild populations and threatened species, representing a concern to biodiversity conservation. Farming practices can destroy the natural structure of the soil, reducing diversity by killing small animals (e.g., insects), bacteria, and fungi that live in the substrate. Moreover, runoff may also carry herbicides and pesticides used in monocultures that can damage aquatic ecosystems, disrupting and killing aquatic wildlife and polluting water sources. Some ecological farming methods that help to reduce biodiversity loss include, among others, the use of natural fertilizers, diversification of crops, biological pest control, etc.

Why do you think leaves have stomata on their underside only? Explain.

Answers

The stomata must be open during the daylight hours to let oxygen and carbon dioxide pass through. While they are open, water vapor escapes into the atmosphere (transpiration). ... Transpiration is the loss of water through stomata, so, more stomata are found on the lower surface to prevent excessive loss of water.

In a lotus plant, stomata is found on the upper epidermis of the leaf.

Stomata are responsible for the exchange of gas with the surrounding atmosphere of the leaf. Their guard cells stay taut during the day to keep the stoma open.

Guard cells can only stay open if they are saturated with a certain quantity of water.

From this information we can infer that stomata are typically found on the lower epidermis to prevent water damage when it rains.

The rain would not only cover the openings, it would also ruin the osmotic balance of the guard cells causing inefficiency and damage to the cycle of gaseous exchange.

Natural selection probably selected against such plants giving rise to those with stomata on the underside.

Not really sure about this answer so can someone give me the correct one​
