If a heterozygous plant seed color (Rr) is crossed with a homozygous recessive plant (rr), what is the probability of each seed color being produced?

Answers

Answer 1

Answer: If you draw the chart that crosses which genes each offspring would receive, the answer would be Rr, rr, rr and rr. With that you would say there is a 1 in 4 chance of getting Rr and 3 in 4 chances of getting rr.

Answer 2

Answer:

Answer:

Explanation:If a heterozygous plant for seed color (Rr) is crossed with a homozygous recessive plant (rr), what is the probability of each seed color being produced? ... The probability will be ½ for each seed color.

Cynthia, a 55 kg woman, is training to run a marathon. How many grams of carbohydrate does she need during periods of heavy training?

Answers

It is recommended to eat about 4 grams of carbs for every pound of body weight per day. So, it means that Cynthia (55 kg ~ 121 pounds) needs to take in about 500 grams of carbohydrates daily. Carbohydrates are important nutrient for marathon athletes to consume when preparing for a marathon because the skeletal muscles are fuelled mainly by glucose derived from carbohydrates. Glucose is stored in the form of glycogen to promote a decrease in fatigue during the race.

Answer: 485.16 grams of carbohydrates.

Explanation: The energy requirement of the body is fulfilled by the food that we eat. Carbohydrates are the main source of energy for the body.

The women weights 55 kilograms which means it weights 121.25 pounds.

1 pound of wight requires 4 grams of carbohydrates

So, 121.25 pounds will require 485.16 grams of carbohydrates for her heavy period of weight training.

C. Savanna and grassland

An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.
A biome is composed of various diverging ecosystems that relates with the community. Biomes can either be deserts, grassland, savanna, tropical rain forest, taiga, boreal and etc.

When pollen moves from the _____ to the _____, fertilization can occur. pistil; stamen anther; stigma style; stamen?

Answers

Answer: The correct answer for the blank is- Anther, stigma.

Fertilization ( process of fusion of male and female gamete) in flowering plants takes place when pollen ( containing male reproductive cell that is sperm) produced from anther ( male reproductive part) is transferred to the stigma ( a part of female reproductive system).

It then moves through a pollen tube ( style) that follows stigma and enters the ovule ( bearing eggs) of the ovary. Finally, fusion of male and female gamete takes place.

from the anther to the stigma! hope i helped
