Approximately time passes between B and F
Answer:
14 days
Explanation:
It takes 27 days for the moon to make a full rotation around the earth. Because half the of the rotation around the earth has been made, half 27. Half of 27 is 13.5, so the time between B and F is approximately 14 days.

A siamese cat can be one of three colors. Black(B) , Orange (O) or black and orange(BO).
What will be the result of crossing a purebred orange siamese cat with a hybrid (BO)?
Offspring Genotypes
Offspring phenotypes?
What type of inheritance is this?
Answer:
Offspring Genotypes - ½ BO : ½ OO
Offspring phenotype - ½ Black orange cat : ½ orange cat
Type of inheritance - Co-dominance
Explanation:
This question involves a single gene coding for skin color in Siamese cat. The alleles for orange color (O) and black color (B) are co-dominant i.e. they are both expressed in a heterozygous state.
According to the question, a purebred orange siamese cat (OO) was crossed with a hybrid cat (BO). The following gametes will be produced by each parent:
OO - O only
BO - B and O
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced from this cross:
½ BO : ½ OO
½BO - Black orange phenotype
½OO - Orange phenotype
- This type of inheritance is CO-DOMINANCE

Which of the following Identifies a water link between agriculture and urban need?
the loss of land used to construct new buildings
the loss of income from Import and export of food products
the loss of market value for agricultural products that are over produced
the loss of marshes and bogs that provide sources of freshwater used for drinking
Answer:
the loss of mashes and bogs that provide sources of freshwater used for drinking.
As the question says about the identification of a water link between agriculture and urban needs.
A source of freshwater is needed to obtain water ; thus loss of mashes and bogs that provide sources of freshwater used for drinking is the answer.
Answer:the loss of mashes and bogs that provide sources of freshwater used for drinking.
Explanation:
There are now several effective antimalarial drugs that can treat people who have malaria or prevent them from getting the disease altogether. Predict what will happen to the frequency of the sickle cell allele over the next 100 years as these drugs become more widely used by people living in areas where malaria is endemic: _____________ Predict what will happen to the frequency of the sickle cell allele over the next 100 years in areas like Boston MA, where there is no incidence of malaria: __________ stay the same ; stay the same decrease ; increase increase ; increase increase ; decrease decrease ; decrease
Answer:
decrease, decrease
Explanation:
By using antimalarial drugs in order to prevent malaria, the frequency of the sickle cell allele decreases in both areas where malaria is endemic and the areas where no incidence of malaria occurs because there is no necessity of sickle cell allele in the population to prevent malarial disease. Sickle cells have high significance in prevention of malarial diseases so when there is no malaria happens in the population so there is no need for it and the allele slowly removed from the population and decrease occurs in its frequency.
What is the correct mRNA transcription of the following DNA sequence? ATGGCACCTTAC
A. UACCGUGGAAUG
B. AUGGCACCUUAC
C. CAUUCCACGGUA
D. CATTCCACGGTA
The process of transcription produces the mRNA sequence from the DNA. The mRNA transcription of ATGGCACCTTAC will be UACCGUGGAAUG. Thus, option A is correct.
What is mRNA transcription?Transcription is the process of the formation of mRNA from the replicated DNA strand of the cell. It produces an mRNA transcript that is a single strand and further codes for amino acids.
The mRNA transcript forms by the base pairing with the DNA template. If the DNA sequence is ATGGCACCTTAC then according to the base pairing rule the adenine (A) pairs with uracil (U) in mRNA, and guanine (G) pairs with cytosine (C). In mRNA, the adenine binds with uracil and not thymine, and hence A pairs with U, whereas the G-C bond remains the same.
The DNA strand: ATGGCACCTTAC
The mRNA sequence will be: UACCGUGGAAUG
Therefore, option A. UACCGUGGAAUG is the mRNA transcript.

How do the organs of the excretory system work together to eliminate potentially harmful wastes from the body?
Answer:
This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.

Name 3 organisms that would be classified as eukaryotic multicellular and heterotroic
Answer:
PROTIST, FUNGI, PLANTS
Explanation:
The Protist Kingdom consists of mostly unicellular organisms that can have characteristics similar to plants, animals or fungi. Characteristics of Protists: mostly unicellular, few multicellular, eukaryotic, can be heterotrophic or autotrophic. Ex: algae, Paramecium, kelp (multicellular).
The three types of organism that would be classified as eukaryotic multicellular and heterotroic should be protist, fungi, and plants.
What is the Protist Kingdom?It should treated as the unicellular organisms that contains the attributes, similar kind of the plants, animals, or fungi.
The attribute of protists involved the unicellular, less multicellular, eukaryotic, heterotrophic or even autotrophic.
These organisms are classified together since they are made up of eukaryotic cells.
Therefore, the above should be considered as the protist, fungi, and plants.
