complementary strand of DNA?
DNA Strand 1: AATCGGTAC
Answers
Answer:
TTAGCCATG
Explanation:
Deoxyribonucleic acid (DNA) is a double helix molecule made up of two complementary polynucleotide strands oriented antiparallel to each other. Each nucleotide in both DNA strands is composed of a five-carbon sugar (deoxyribose), a phosphate group and a nitrogenous base. In DNA, there are four types of nitrogenous bases: Thymine, Guanine, Adenine and Cytosine (in RNA, Uracil replace Thymine). According to the base-pairing rules, Adenine always pairs with Thymine through two hydrogen bonds, whereas Guanine always pairs with Cytosine through three hydrogen bonds.

At a chemical synapse, the intensity of the stimulus is coded by _______. At a chemical synapse, the intensity of the stimulus is coded by _______. the amount of calcium that enters the axon terminal the amount of neurotransmitter released and the amount of calcium that enters the axon terminal the amount of neurotransmitter released the size of the action potential the size of the action potential and the amount of neurotransmitter released
Answers
Answer:
The correct answer is - the amount of neurotransmitter released and the amount of calcium that enters the axon terminal.
Explanation:
The intensity of the signals or stimulus depends on the amount of the neurotransmitter such as acetylcholine, dopamine and the amount of calcium that enters the axon terminal.
A neurotransmitter is a chemical that carries, boost or balance a signal and send stimulus or signals throughout the body. When an action potential reaches the nerve terminal calcium channels open and enters.

Explanation:
In a haplodiploid mating system, how can the coefficient of relatedness between two sisters be 0.75 (75%)? Females are haploid, and they pass on 100% of their genes, whereas males are diploid and pass on 50% of their genes, meaning that the coefficient of relatedness is 0.75. Females can reproduce asexually, meaning they produce clones, and those clones share on average 75% of the genes of their sisters. If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes. Male and female bees are both diploid. The males contribute 100% of their genes to their offspring, and females contribute 50%. Therefore, each female offspring shares 75% of her genes with her sister siblings on average.
Answers
Answer:
If a queen mates with a single drone, then all the resulting females have all of the same genetic contribution from the male, since males are haploid and contribute 100% of their genes
Explanation:
Haplodiploidy is a type of sex-determination system where males are haploid (i.e., they contain only a set of chromosomes 'n') and develop from unfertilized eggs, whereas females are diploid (i.e., they contain two complete sets of chromosomes '2n') and develop from fertilized eggs. The bees show this haplodiploid system of sex determination, which is quite common to many hymenopterans. In bees, workers and queens are diploid (2n) females and contain 32 chromosomes, a set of 16 chromosomes is contributed by the queen's egg, and another set of 16 chromosomes is contributed by the drone sperm (16 + 16 = 32 chromosomes). On the other hand, drones are haploid (n) males and contain only one set of 16 chromosomes, which is exclusively contributed by the queen's egg.

B. the bats in the United States had a more deadly form of the fungus. C. the bats in Europe and China were dying at a faster rate. D. the bats in Europe and China were healthy.
Answers
Answer:
The correct answer is - D. the bats in Europe and China were healthy.
Explanation:
The white-nose disease of bats is caused by the Pseudogymnoascus destructans or Pd fungus that found in cold mines and caves of the bat. It is a fatal disease that leads to the destruction of the bat population in the United States, in north Calorina the population was dropped up to 99 percent. The bats found in Europe and China with the Pd fungus were healthy and do not cause any fatal disease in the population.

Answers
Answer:
DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.

Explain how the following events could be important in the formation of a new community of living things:
a) Fish-eating birds land on rocky islands
b) A coconut is washed up on a beach
c) An especially high tide washes seaweed onto a sandy beach
Answers
Answer:
The secondary succession.
Explanation:
It one of the ecological successions of a plant life that take place on the primary or disturbed system as the succession occurs in the preexisting soils as here the preen of the rocky island and the sandy beach is considered to be the primary succession where the coconut is washed by the high tides along with the seaweed.
The secondary succession thus starts to form with the interaction of the and beach as the coconut will continue and grow in the sandy beach as it will get nutrient and moisture firm the soil and gradually develop into a large island of coconut palm trees and thus the rocky beach will get converted to a secondary living community.
Ecotourism can provide an incentive for local people to preserve the environment in order to attract more visitors, but sometimes development is done with little planning for long-term environmental impacts.

A. Investigate the ecological impacts and gather evidence on which to base their decisions
B. Hire an agent to locate a suitable property and start developing infrastructure
C. Market the development to investors and explain ecotourism to them to raise money for the resort
D. Determine what types of activities the resort will offer and hire staff
Answers
Answer: The next steps in their plan should be to (Investigate the ecological impacts and gather evidence on which to base their decisions). The correct option is A.
Explanation:
ECOTOURISM is defined as the visitation of individuals (tourist) to natural areas that conserve the environment and sustains the well-being of the local people. It has to do with the interaction of the biotic components of the natural environment by tourists. This has the advantage of providing an incentive for the local inhabitants but can cause a long term negative environmental impact of not properly planned.
Conservation of these natural resources improves the quality of lives. It enables the inhabitants to live in a clean and healthy environment (eco-friendly). To set up a tourism center, certain rules and regulations needs to be met in order to avoid endangering both the biotic and abiotic components of the ecosystem. Therefore these local groups should investigate the ecological impacts and gather evidence on which to base their decisions. This would help conclude if a particular selected environment is conducive.

Answers
Answer:
Option a. "2"
Explanation:
Answer:
Mitosis requires the chromosome to be replicated into 2 copies.
option a is the answer
Explanation:
The cell separates the copied chromosomes to form two full sets (mitosis) and the cell divides into two new cells (cytokinesis). The period between cell divisions is known as 'interphase'.The genome is composed of a number of chromosomes—complexes of tightly coiled DNA that contain genetic information vital for proper cell function. Because each resultant daughter cell should be genetically identical to the parent cell, the parent cell must make a copy of each chromosome before mitosis
