Patrick , who is In starfish, pink boy color(P) is dominant to orange(p) , and thick eyebrows(T) are dominant over thin(t) ones. Patrick , who is heterozygous for body color but purebred for thick eyebrows , has met Patti , who is recessive for both traits. for body color but purebred for thick eyebrows , has met Patti , who is recessive for both traits. show the cross
Answer:
Explanation:
From the given information;
Pink boy color = P = dominant
orange boy color = p = recessive
Also; for eyebrows:
thick eyebrows (T) is dominant over thin eyebrow t i.e. (recessive)
However, if Patrick = heterozygous for body color i.e. Pp but purebred for thick eyebrow, i.e. TT crosses with;
Patti who's recessive for both traits,
i.e. pp for body color and tt for thin eyebrow.
Then the punnett square cross can be computed as follows:
For Patrick :
Pp × TT = PT PT pT pT
For Patti
pp × tt = pt pt pt pt
PT PT pT pT
pt PpTt PpTt ppTt ppTt
pt PpTt PpTt ppTt ppTt
pt PpTt PpTt ppTt ppTt
pt PpTt PpTt ppTt ppTt
Cichlids, a type of fish, were introduced to a lake around 200 years ago. Over the years, the fish have developed into two distinct groups. One group stays in the main lake and the other group resides in the streams that flow into it. Both groups of cichlids breed in the same streams at the same time of year. However, the groups are splitting into two genetically and physically different types of fishes. How would you classify this type of speciation
Answer:
sympatric speciation
Explanation:
Different sympatric species have the same closest ancestor and live in the same area but inhabiting different niches.
The steps for sympatric speciation are:
An ancestral species inhabit a geographic area.With time, different populations of the same species occupy different niches or microhabitats in this general area. As the microhabitats are different, they have different environmental pressures that are acting on each population.These pressures lead to the origin of differences between groups, which need to adapt to each environmentEach population suffers genetic changes due to environmental conditions. These changes are inheritable.With time, these differences drive to the final complete divergence of populations, becoming different species and reproductively isolated.In sympatric speciation, the interruption of genetic flow must be fast, and there must be differences in niches so no species can compete and displace the other species. Speciation occurs in the same distribution area of the original species. The new species originate in a place with no physical barriers but different environmental pressures.
In the exposed example,
The introduced Cichlid fishes 200 years ago → Original species and the common ancestor between the new derivated speciesThe lake → general geographic areaThe main lake and the streams → Microhabitats or niches with different pressures eachThe groups are splitting into two genetically and physically different types of fishes. They do not mate. There is no genetic flow between groups. → Speciation process.Use the scenario to answer the question.

How is the formation of RNA similar to DNA replication?
Answer:
Both DNA replication and Transcription involve the generation of a new copy of the DNA in a cell. DNA transcription is involved in replicating the DNA into RNA, while the DNA replication makes another copy of DNA. Both the process is involved in the production of new nucleic acids- DNA or RNA.
Explanation:
The formation of RNA is similar to DNA replication because both processes require an analogous enzyme (Polymerase).
What is DNA replication?DNA replication refers to the process of duplication of the genetic material before cell division (either mitosis or meiosis).
DNA replication requires different enzymes such as DNA polymerase, ligase, RNA primase and topoisomerase. Moreover, RNA replication or transcription also requires a nucleotide polymerase (RNA pol), which uses DNA as a template to generate complementary RNA.In conclusion, the formation of RNA is similar to DNA replication because both processes require an analogous enzyme (Polymerase).

The purpose of Phase II in rehabilitation is to control inflammation.
O a. True
O b. False
The correct answer is False.
Explanation
Rehabilitation has three main phases, the first of which is the first response to an injury, so the main objective in this phase is to defend the body against harmful substances, eliminate dead or dying tissue and promote the renewal of normal tissue. as well as alleviating pain, controlling the inflammatory response to injury and protecting the affected anatomical area. So you have to clean the wound, disinfect it, cover it, and in cases where it is required to put ice to reduce inflammation.
In the second phase the recovery of functional losses, so it is necessary to start making small movements in the affected area to reactivate its functions progressively.
The third phase is advanced rehabilitation in which functional training work begins with the aim of strengthening and putting the affected area back in a movement directed towards sports practice.
Therefore, the correct answer is False, because the inflammation control is done in Phase I and not in Phase II.

A mom, heterozygous for type B blood, has a baby with type AB blood, what possible blood types could the baby's father have?
Select all that apply
O
A
AB
B
Answer:
A
AB
Explanation:
This question involves blood type, which can either be blood type A, B, AB or O in humans. Alleles A (iA) and B (iB) are co-dominant but dominant over allele O (i).
According to this question, a mom who is heterozygous for type B blood i.e. genotype iBi, has a baby with type AB blood. Since the mother contributed the "B" allele, it means that the father contributed the A allele. Only a father with genotype: iAi or iAiA (type A) or iAiB (type AB) can produce such allele.
Why is it difficult to avoid a tsunami?
Answer:
It is difficult to avoid a tsunami due to it being such a large volume of water that is capable of destroying a large amount of land.
Explanation:
However, even though it is difficult to avoid a tsunami, as they are extremely difficult to predict, there are ways where one can begin to prepare before it hits. One of the ways you can do this is getting to a higher ground far away from inland, avoiding downed power lines, and steering clear of buildings or bridges where large, heavy objects could fall during an aftershock.
Tsunamis are incredibly dangerous, since there is a great chance that if you get caught in one, you can drown. Since tsunamis have little to no warning when they arrive, it is always essential to be prepared when one strikes.

The cladogram shown below describes the evolutionary relationship among several species, labeled A to F. The five dots represent derived characters.
A cladogram includes a line with 5 dots. From bottom to top, the dots are labeled Trait 1 to Trait 5. Branches from the line lead to tips labeled A to F. Labels C and D are at the ends of very short branches off a longer branch.
The cladogram supports which of these predictions about the genomes of the six species?
A. The genome of species E is equally similar to the genomes of species D and F.
B. The genome of species E is more similar to the genome of species F than to any of the other species.
C. The genomes of species C and D are nearly identical because neither species has a derived character.
D. The genomes of the six species share few, if any, DNA sequences.
(You will find the cladogram in the attaches files)
Answer:
C. The genomes of species C and D are nearly identical because neither species has a derived character.
Explanation:
A Cladogram is a tree-type graph based on cladistic analysis. It represents the common ancestral relationships among the involved groups.
The tree-type graph is a ramified diagram that represents the relationship between the involved taxa. The cladistic analysis follows the maximum parsimony criterium. Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes. It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny. The sequencing term refers to lists of groups according to their relation. One group is the brother-group of the following one.So the cladogram represents the relationship between groups according to a derived character.
The derivated character is any trait that a group passes to the descendants. Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.
A cladogram provides an image of how new species keep characters that were inherited from older species.
So, in the exposed example, the five dots represent derived characters, representing traits 1 to 5. Branches A to F, represent groups. (See the cladogram in the attached files). Group A inherited trait 1, group B probably still carries trait 1, but also trait 2. Groups C and D equally inherited trait 3. Group E inherited character 4, and finally, group F inherited character 5.
Groups C and D inherited trait 3 and probably also still have traits 1 and 2. So they are very similar to each other. At a certain point, they diverged, probably due to a new mutation that was not passed to the rest of the group.
C. The genomes of species C and D are nearly identical because neither species has a derived character. Correct.

Due to the tissue loss, a distinct line of bare white skeleton developed, which is how the disease got its name. The reef's food source changes when the corals are removed, changing the species makeup totally.
What is the cause of White band infection?A bacterial condition called the “white plague” is frequently mistaken for coral bleaching. According to recent investigations, the sickness comes in many forms. Corals lose tissue in every situation, exposing their exposed, raw, white skeleton.
Coral illnesses can spread through a variety of routes, including direct contact, water- or vector-borne transmission, and the relative weights of these routes can vary over time and across geographical areas and disease systems.
Therefore, A solid indication that an infection is present is if your band cell count is more than 10%. To identify the underlying cause of your bandemia, your doctor will advise more diagnostic procedures.
