Baby with blood group O belongs to Mr. and Mrs. Jones, baby with blood group B belongs to Mr. and Mrs. Williams, and baby with blood group AB belongs to Mr. and Mrs. Wilson.

Blood group or blood type is the classification of the blood cells into different classes on the basis of presence or absence of antibodies and antigens on the membrane of the blood cells.

The alleles which can be formed in case of Mr. and Mrs. Jones are AA or Ai type. These alleles can only result into formation of an offspring with blood group O or A. Similarly, the possible combination of alleles in case of Mr. and Mrs. Williams is AB and ii, these combinations will result into development of offspring with blood group A or B. In case of Mr. and Mrs. Wilson, the possible combinations of alleles are Ai or AA and Bi or BB, which results into formation of offspring with blood group AB.

A crowded living environment will require a lot of energy to move in to because there is more competition for job positions, habitation and resources. Also, it creates an environment where moving around can become a challenge, because there may be traffic and other phenomena that's caused by a crowded population. Managing a crowded environment also can be more challenging to governors and authorities, maybe providing your daily routine with structural problems such as floods and other types of consequences if there is a disorganisation on managing. Therefore, yes, moving into a space that is very crowded require a lot of energy.

The substitution of a single nucleotide in the GULO coding region results in a stop codon. This results in a smaller nonfunctional protein

The substitution of a single nucleotide in the GULO coding region results in a stop codon. This results in a smaller nonfunctional protein.

With the use of modern genomics, it is possible to examine damaged metabolic pathways by screening the DNA of a wide range of organisms. The abundance of data has shown that the genetic entropy in human and other genomes is widespread.

Humans, apes, guinea pigs, bats, mice, rats, pigs, and passerine birds all have deletions in the GULO (L-gulonolactone oxidase) gene that result in loss of the vitamin C pathway.

According to recent studies and the data presented here, various GULO exon deletions in humans, chimpanzees, and gorillas all happened separately in each taxon and are connected to areas that contain a wide range of transposable element fragments.

Therefore, The substitution of a single nucleotide in the GULO coding region results in a stop codon. This results in a smaller nonfunctional protein.

Answer:

A scientific law describes an observed pattern found in nature without explaining it. The theory is the explanation.

Explanation:

Paul's focus on the relationships between living organisms and their environment suggests that he is studying the ecological perspective on human development.

This approach to understanding human development emphasizes the ways in which individuals and their environments interact, and how these interactions shape an individual's physical, social, and cognitive development.

The ecological perspective on human development is rooted in the work of Urie Bronfenbrenner, who developed the ecological systems theory in the 1970s. Bronfenbrenner's theory emphasizes the importance of multiple levels of environmental influence on human development, including the microsystem, mesosystem, exosystem, and macrosystem. The microsystem includes the immediate settings in which an individual interacts, such as the family, school, and peer group.

The mesosystem encompasses the interactions between these different settings, while the exosystem includes broader societal institutions that indirectly affect an individual's development, such as the legal system or media. Finally, the macrosystem refers to the broader cultural and historical context in which development occurs.

Answer:

The white one as it would blend in better ie be camouflaged and less at risk to be eating by a predator

Explanation:

The moth that would survive in the bunch of trees pictured is white pepper moth.

Camouflage, also known as cryptic coloration, is a defence or tactic used by organisms to conceal their appearance, usually in order to blend in with their surroundings.

Camouflage is used by organisms to conceal their location, identity, and movement. This enables prey to avoid predators while also allowing predators to sneak up on prey.

The peppered moth (Biston betularia) is a night-flying moth found in temperate regions.

The light-colored moths were difficult to see as the soot lightened the trees.

They were less likely to be eaten by birds, whereas dark-colored moths could blend in better on darker trees. As a result, dark-colored moths had a lower survival rate.

Thus, there is better survival rate of white moths in the given scenario.

Answer:

a theory

Explanation:

A hypothesis that has support to back it up and that is yet to be disproved can be referred to as a theory.

Ordinarily, a hypothesis is a tentative statement that has not been proven in any way. Once a hypothesis has supports to back it up and there are no counter-evidence to disprove it, it becomes a theory.

In other words, a theory is a proven hypothesis and it remains so until there are overwhelming evidence to counter the supporting evidence.

Bacteria can quickly divide by means of binary fission. Because of this, following binary fission reactions, every child will have the same genetic makeup. Option C provides the right response.

The most common method of cell division in unicellular organisms is binary fission. It closely resembles the mitotic division that occurs in multicellular animals. DNA is copied when bacteria divide by binary fission.

A particular asexual mechanism of reproduction is binary fission. In binary fission, the parent cell's nucleus and cytoplasm divide after which two new daughter cells are created. It is observed in single-celled creatures including amoebas, paramecium, and others.

Because DNA replication and DNA separation occur simultaneously during binary fission, the newly created cells are identical to one another.

Complete question:

Bacteria can reproduce quickly by means of binary fission. Because of this, after binary fission

A) the offspring will have traits of both parents.

B) there is genetic variation among the offspring.

C) all the offspring will be genetically identical.

Some plants can fling, squirt, or otherwise hurl their own seeds for some distance upon maturity. The maximum distance a seed is likely to travel using this mechanism is about 45 meters.

Seed dispersal is the process by which seeds are distributed throughout a landscape. Seeds that are spread by plants are said to be dispersed, and they can be dispersed by a variety of methods, including wind, water, and animals. A seed's form can influence how it is dispersed.

The maximum distance a seed can travel using this mechanism is around 45 meters. Several plants fling their seeds, which are commonly referred to as ballistic dispersal mechanisms. The plants that fling their seeds include violets, touch-me-nots, and witch hazels, among others.

When the seeds are mature, the seedpod splits open, and the seeds are flung out. In the case of touch-me-nots, the slightest touch may cause the seeds to fly out from the seedpod. Seeds may travel significant distances if they are dispersed in this manner.

Organelle I is the ribosome, which is responsible for protein synthesis. Organelle III is the mitochondrion, which is involved in energy transformation and energy production through cellular respiration.

Organelle I, which is labeled as the ribosome, is responsible for protein synthesis. Ribosomes are involved in the process of translation, where they read the mRNA (messenger RNA) and assemble amino acids into polypeptide chains, ultimately forming proteins.

Organelle III, which is not specified in the question, cannot be identified based on the provided information. However, if we assume it refers to mitochondria (as labeled with Roman numeral VI), then its function is energy production.

Mitochondria are the powerhouses of the cell and are involved in cellular respiration, a process that generates ATP (adenosine triphosphate), the primary energy currency of the cell.

Therefore, the correct functions for organelle I (ribosome) are protein synthesis, and for organelle III (mitochondria) are energy production.

Answer:

True

Explanation:

It is typically a final step to remove organisms from the treated water before the effluent is released back into the water system. Disinfection prevents the spread of waterborne diseases by reducing microbes and bacterial numbers to a regulated level.

Disinfectants are used to rapidly kill bacteria. They kill off the bacteria by causing the proteins to become damaged and the outer layers of the bacteria cell to rupture. The DNA material subsequently leaks out.

Disinfection is the process designed to kill or inactivate most microorganisms in wastewater, including essentially all pathogenic organisms. Contrast this to sterilization, which is the removal and destruction of all living microorganisms, including pathogenic and saprophytic bacteria, vegetative forms and spores.
