What are some short-term effects of the decline in the bee populations?

Biology
1 answer:
Anestetic [448]3 years ago
5 0

Answer:

Other pests and parasites like tracheal mites, small hive beetles, and wax moths, as well as the disease nosema, are also having a negative impact on the health of the honeybee population. Hive beetles are native to the sub-Saharan areas of Africa but have been found outside of the region around nests of the honeybee.

ALL BUT one product of the light dependent reaction of photosynthesis is utilized in the light independent reaction. That is
Lesechka [4]

Answer: Oxygen

Explanation: Photosynthesis is a process by which plants use carbon dioxide, water and sunlight to produce glucose and oxygen.

Photosynthetic reactions are divided into two phases: 1). light dependent reactions and 2). light independent reactions.

1) In light dependent reactions, chlorophyll and other light absorbing pigments absorb light energy and conserve it as ATP and NADPH with the simultaneous liberation of oxygen. This reaction occurs only when plants are illuminated. In light reactions, light energy is used to split water molecules into hydrogen ions and oxygen, the hydrogen ions produced are transferred to NADP+ to form NADPH, ATP is also produced in light dependent reactions.

2) In light independent reactions, ATP and NADPH produced in the light dependent reactions are used to drive the light independent reactions in which ATP and NADPH are used to reduce CO2 to form trioses, starch, sucrose and other products derived from them.

Which of the following is a correct DIFFERENCE between sexual and asexual reproduction?
jolli1 [7]

Answer:

A. Sexual Reproduction creates genetically different offspring.

Explanation:

Sexual Reproduction is created through 2 different opposite parties, in which the product takes around half of the genes from each individual parties. The traits that are shown are then decided on whether or not they are dominant or recessive or non-existent.

In a Asexual Reproduction, the reproductive capabilities of both parties are found inside one organism. The organism is able to produce both the sperm and egg, and therefore do not need a partner to reproduce. This means that the DNA inside the body is the only source for production, and that there will be very little variation in the DNA.

If a dna analysis reveals that a cell has 60 ng of adenine and 20 ng of cytosine, how much thymine and guanine are in the cell?
Serggg [28]

Answer:

Thymine= 60 ng

Guanine= 20 ng

The complementary base pairing occurs between adenine and thymine and guanine and cytosine bases.

Explanation:

According to the Chargaff rule, a double-helical DNA molecule has an equal number or equal amount of adenine and thymine bases since adenine always pairs with thymine. Similarly, the amount of guanine base is equal to that of the cytosine base.

Chargaff rule is based on the complementary base pairing between purine and pyrimidine bases. According to the given information, the amount of adenine is 60 ng. Therefore, the cell would have 60 ng thymine. Similarly, the amount of the cytosine base in the cell is 20 ng which means that the cell would have 20 ng of guanine base.
