Two first the sponge can claim are
1. reproduce sexually
2. combine sperm and egg
The Sponge belongs to the Phylum Porifera of the Animal Kingdom. These are the first organisms in the animal kingdom who can reproduce by sexual reproduction and shows male and female gamete formation.
The Sponges are the members of the phylum Porifera of the Animal kingdom. Sponges are the basal animal clade and the sister of the diploblasts. These are multicellular organisms whose bodies are fully-covered with the pores and channels that allows water to circulate through them. A layer consisting of jelly-like substance is sandwiched between two thin layers of cells in the body cavity of these organisms.
Sponges are the first organisms in the animal kingdom that can reproduce by the sexual mode of reproduction. Sexual reproduction involves the formation of gametes and their fusion to form the zygote. This zygote leads to the formation of new organism.

This substitution score matrix called _____ is derived from protein families that are characterized by blocks of conserved amino acid sequences.
Answer:
BLOSUM
Explanation:
A substitution matrix is a matrix used in bioinformatics (and also in computational biology) to determine/estimate the rate at which one character -which is specified by a nucleotide sequence in nucleic acid alignments or by one amino acid in protein alignments-, changed to another character during the course of the evolution. The BLOcks SUbstitution Matrix (popularly known as BLOSUM) is a substitution matrix used to score one amino acid for another in a protein alignment. The BLOSUM substitution matrix is particularly useful to compare evolutionarily conserved regions between protein sequences and thus score their alignments, where each entry is indicated by a similarity score between two amino acids.

g With respect to their 3' and 5' ends, the two polynucleotide chains of a double-stranded DNA molecule are:
Answer:
They are antiparallel
Explanation:
They are antiparallel because one strand of 3' faces the end of 5' of another strand and 5' end of one strand faces 3' end of another strand. Which indicate that 5 phosphate group faces the end of 3 hydroxyl group and they are of opposite directions to each other because it has opposite polarity with each other .

Do you believe that all of our actions can be attributed to the nervous system? Does your memory of an event trigger your responses? Why or why not?
Answer:
The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.

Answer: The correct option is C.
Cloning vectors.
Explanation:
Viruses are use as cloning vectors because they can give the new gene or birth the new gene by infecting the cell. They are so modified and orogrammed in such a way that they cannot cause disease when it is used in humans. Cloning vector is a DNA fragment gotten from viruses or bacteria plasmid which is maintained and used for cloning purposes.

True breeding plant round seeds (DD) were bred with true breeding smooth
seeds(dd) to produce F1 offspring. F1 offspring were then bred with other F1
offspring. What is the genotypic ratio of the resulting F2 offspring? What is the
phenotypic ratio of the resulting F2 offspring?
Answer:
Genotypic ratio F2 = 1:2:1
Phenotypic ratio F2 = 3:1
Explanation:
In this case, parental genotypes can produce only one type of gamete, i.e., one parent can produce only D gametes, while the other parent can produce only d gametes. Therefore, all F1 generation will be heterozygous (Aa). An F1 hybrid is the first filial generation of offspring obtained from crossing between different parent types. The F1 will produce two gametes (A; a) in a ratio 1:1, thereby the F2 obtained by crossing F1 offspring will have a phenotypic ratio of 3:1 (3 D_; 1 dd) and a genotypic ratio of 1:2:1 (1 AA; 2 Aa; 1 aa).

a. the relative amount of products and reactants.
b. the formation of glucose.
c. the intermediate reactions needed to break down glucose.
d. the environment in which cellular respiration occurs.
The chemical equation of cellular respiration comprises information regarding the relative amounts of products and reactants.
• The process, which takes place within the mitochondria of all the organisms is termed cellular respiration. In this process, the simple sugars are dissociated into water and carbon dioxide and release energy in the form of ATP.
• A chemical reaction is a procedure in which one or more components, that is, the reactants get transformed into one or more different components called the products.
• The substances, which start the reaction are called reactants, while the ones that get produced in the reaction are called products.
• The association between the reactants and products in a chemical reaction can be signified with the help of a chemical equation.
Thus, the chemical reaction of cellular respiration comprises information regarding the relative amount of products and reactants.

ATP is to your cells as ______ is to a car
Answer:
Gas to a car
Explanation:
The ATP function in the cell is equal to the gas or fuel function in the car, as the ATP gives energy to the cell for different functions like the fuel gives energy to the car to move from one place to another.
What is the function of the ATP?
ATP is produced in the cell from the food that living organisms, such as animals and plants, consume and use to produce ATP. There are different reactions that together make ATP, such as glycolysis, the Krebs cycle, and the electron transport chain, and with the help of ATP synthase, ATP is made. It performs a variety of cellular functions, including protein synthesis, food digestion, message transmission from one cell to another, and so on.
Hence, the ATP function in the cell is equal to the gas or fuel function in the car, as the ATP gives energy to the cell for different functions.
