5. Two parents, one with type B blood and one with type A blood, have a child with type O blood. Which statement explains how this can occur?
Answer: Two parents, one with type B blood and one with type A blood.
Explanation: They both have different blood types, so that leads to the child having an O blood type.
Hope this helps!!
Sorry if it's wrong!!
Have a great day!!
If the two parents have blood group A and blood group B with their child of type O blood. Then, the possible genotypes of the parents is AO and BO. Thus, the correct option is A.
What is Blood group?A blood type is the classification of blood. Classification of blood group is based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells. These antigens are biomolecules which may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.
There are four main blood groups which are A, B, AB and O. Blood group is determined by the genes a person inherit from the parents. In a cross between one parent with blood type A and one with blood type B having child with blood type O has genotypes AO and BO. The genotype is shown in the punnett square.
Therefore, the correct option is A.

Which statements are true?
1 and 2
2 and 3
2.4 and 5
3.4 and 5
Answer: 2, 4 and 5.
Explanation:
Human system are made of various organs which in turn are made up of various tissues which in turn are made up of various cells. Cells are therefore much more numerous than systems.
As already mentioned, organs are made up of tissues which are made up of cells so statement 4 is right.
As systems are made up of various organs working together, they are more complex than the individual organs. For instance, the Muscular system is more complex than the triceps or bicep muscles.
Could you explain the roles and relationships among producers, consumers, and decomposers, and identify the distinguished characteristics of several common relationships among organisms in an ecosystem near you?
Answer:
A consumer may also eat other consumers as food. When producers and consumers die, the Decomposer will come along to decompose (break down) the bodies of the dead producers and consumers into smaller chemicals - in short treating them as a food source
Explanation:
Your welcome have a good day :)
The producers, consumers, and decomposers are related to each other in an ecosystem in a specific way.
What is an Ecosystem?The interaction between the organisms of different species plays their role in a systematic way as decided by natural selection, which is known as the Ecosystem.
Producers use light energy and inorganic matter to produce food. They are always present first in the ecosystem. Consumers take energy from plants known as herbivores, and also from herbivores known as Carnivores. Decomposers convert dead organic matter into inorganic matter. This inorganic matter helps producers perform metabolic activities. And finally, this cycle goes on.
Therefore, the producers, consumers, and decomposers are related to each other in an ecosystem in a specific way.

If an organism inherits 1 dominant allele from one parent and 1 recessive allele from the other parent, what is it called?
Answer:
heterozygous
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene. Genotypes are described as heterozygous if the two alleles differ.

TMV Assembly Each of these statements is an experimental observation concerning the reassembly of tobacco mosaic virus (TMV) virions from TMV RNA and coat protein subunits. In each case, carefully state a reasonable conclusion that can be drawn from the experimental finding.
a. When RNA from a specific strain of TMV is mixed with coat protein from the same strain, infectious virions are formed.
b. When RNA from strain A of TMV is mixed with coat protein from strain B, the reassembled virions are infectious, giving rise to strain A virus particles in the infected tobacco cells.
c. Isolated coat protein monomers can polymerize into a virus-like helix in the absence of RNA.
d. In infected plant cells, the TMV virions that form contain only TMV RNA and never any of the various kinds of cellular RNAs present in the host cell.
e. Regardless of the ratio of RNA to coat protein in the starting mixture, the reassembled virions always contain RNA and coat protein in the ratio of three nucleotides of RNA per coat protein monomer.
Answer:
Explanation:
tobacco mossaic virus is aa RNA containing virus enclosed in aaprotein coat. in above sttaed experiment when TMV cause infection in tobacco plant is leaves get infected due to replication of virus in its cells. RNA is first converted into complementary DNA and form a double stranded nucliec acid structure. it syntheaize its protein to make new coats and to wrap the newly synthesized RNA, and make a completely infected new virus which we called virion. in any case the number of coats are equal to RNA so that to prepare new viruse. n

HURRY QUICK 28. An herbicide killed 99% of a weed population. Which of the following is the BEST
biological explanation for why some weeds were able to survive? (1 point)
O Some individuals were able to evolve before the spraying.
Each individual occupied a different ecological niche and so some were unaffected.
Genetic variation in the population allowed some weeds to survive.
The spray caused some individuals to mutate, and they were able to survive and
reproduce.
Answer:
Genetic variation in the population allowed some weeds to survive
Explanation:
Herbicides are substances that are used to destroy unwanted plants. Herbicides are also called weed killers. An herbicide killed 99% of a weed population.
Some weeds were not able to survive as genetic variation in the population allowed some weeds to survive.
Examples of contact herbicides are as follows:
1. Diclofop
2. Dinoseb
3. Diquat
4. Paraquat
Analogy and homology are important concepts used in comparing species. Traits are homologous if they are derived, evolutionarily and developmentally, from the same source structure. Traits are analogous if they have similar functions but are derived, evolutionarily and developmentally, from different source structures. A classic example of analogous structures is insect wings and bat wings. Which of the following pairs of structures are analogous and which are homologous?
a. Dorsal fins of porpoise and a salmon
b. Flippers of porpoise and pectoral fins (front fins) of salmon
c. Joined leg of ladybird beetle and a robin
d. Rhesus monkey's tail and human's coccyx
e. Bright red bracts of poinsettia and green leaves of rose
f. Red bracts on a poinsettia and red petals on rose
Answer:
a. analogous
b. homologous
c. analogous
d. homologous
e. homologous
f. homologous
Explanation:
a. Analogous. Porpoises are mammals while salmon are fish. In this case, fins are analogous structures that evolved separately in both groups.
b. Homologous. Pectoral fins evolved from the forearms of tetrapods, and early tetrapods evolved from fish.
c. Analogous. These structures evolved independently through convergent evolution in both groups.
d. Homologous. They are homologous structures that were inherited from a common ancestor (primates).
e. Homologous. Bright red bracts (modified leaves) of poinsettia and green leaves of rose share a common ancestor (i.e., angiosperms).
f. Homologous. They are homologous structures that were inherited from a common ancestor (i.e., angiosperms).
define atomic number and mass number – describe how they differ
Answer:The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.i) Atomic number is the total number of protons present in the nucleus of an atom. It is also equal to the number of electrons for a neutral atom. Example, atomic number of sodium is 11. ii) Mass number is the number of protons and neutrons in the nucleus taken together. For example, mass number of sodium is 23 g/mol.
