Which of the following best describes evidence from comparative embryology regarding embryos of different species that supports the theory of evolution?
They carry out similar metabolic processes.
They develop in similar environments.
They have the same genome.
They share similar development patterns.
Answer: D.
Explanation: Thus, Comparative Embryology provides strong support for the hypothesis that Darwin put forth to explain the apparent similarities and differences he saw among different species, i.e. that these species are the result of an evolutionary process involving selection (now known to be gene based) for structural and In the mid-1800s, Charles Darwin and Alfred Wallace independently concluded that inherited variations in traits, such as a bird's beak shape, may provide better odds of survival in a given niche. Organisms without the advantageous variation are less likely to survive and pass on their genes.

they share similar development patterns

A
Explanation:
When you were translating the mRNA to an amino acid sequence, where in the cell were you located?
And, on which organelle?
Answer:
It occurs in the organelle ribosome which can either be located in the cytoplasm or in the rough endoplasmic reticulum
Explanation:
This is because the translation of mRNA into amino acids forms proteins and as we know the organelle ribosome is responsible for synthesizing proteins
Finn listed two of the three steps involved in gene therapy. 1. The normal allele is removed from the chromosome. 2. The normal allele is added to the cells of a person with the disorder. Which step should he also include, and where?
Answer:
The unhealthy gene sequence is cut from the DNA before 2
Explanation:
Gene therapy refers to genetic engineering techniques aimed at introducing exogenous nucleic acids (either DNA or RNA) into the patient's cells in order to restore gene function. Gene therapy techniques hold a great promise to treat genetic diseases and disorders. Gene therapy may involve replacing defective genes with a functional copy of the gene of interest within the desired cells. For this purpose, it is required to use a DNA-specific damaging agent to knock out the defective gene and subsequently restore normal gene function by inserting a functional gene sequence into the recipient cells. Gene therapy techniques can be divided regarding target cells into 1-somatic gene therapy, where genetic modifications are applied on somatic body cells (and therefore they are not inherited by offspring), and 2-germinal gene therapy, where genetic modifications are applied on germinal cells (i.e., gametes) or undifferentiated stem cells (and therefore genetic changes may pass to the following generations).

Climate change is predicted to have an impact on Earth's biodiversity. What could be a
consequence of climate change on marine biodiversity?
Answer:
Effects on Ocean Biodiversity
Rising sea levels will also cause changes to ocean temperatures and perhaps even currents. ... In addition, increased carbon dioxide causes acidification of the ocean, affecting creatures and plants that are sensitive to pH imbalances.

2. Bacteria eat the dead bodies of organisms to release the organisms’ stored energy into the atmosphere.
3.Some energy is transferred to the smaller organisms, and the rest is stored in the bodies of larger animals.
4.Some energy is transferred to the organisms, and the rest is released by plants in the form of carbon dioxide.
5.Bacteria eat the dead bodies of organisms, obtain all the energy, and store it in their bodies.
Answer:
3.Some energy is transferred to the smaller organisms, and the rest is stored in the bodies of larger animals.

Patient 1 has Type ___ blood.
Answer:
A.
Explanation:
Patient 1 has Type A blood because agglutination occurs due to reaction with anti-B. We know that A blood group has antigen A and it is anti-B means that they attack on B type of blood cells while on the other hand, B blood group has antigen B and it is anti-A means that they will attack on the A type blood cells upon mixing. So according to the chart, there is nothing happens by reaction of the blood with anti-A whereas agglutination occur by reaction with anti-B so we can say that the patient has type A blood.

Which of the following is a true statement?
A. Disruptions in an ecosystem are normal and natural changes.
B. Disruptions in an ecosystem are caused by both human activity and environmental disturbances.
C. Ecosystems are complex, interactive systems that include both biotic and abiotic components of the environment. D. All of these are true statements.
Answer:
All the statements are true and the correct option is;
D. All of these are true
Explanation:
Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities
An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system
An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity
Therefore all the statements are true.

Plz help
Answer:
The ability of a microorganism to tolerate the effects of an antibiotic is known as antibiotic resistance. It's a certain kind of drug resistance. Antibiotic resistance develops naturally through random mutation, but it can also be engineered by putting a population under evolutionary stress. Bacteria will then transmit genetic information in a hominid-like manner once such a gene has been formed. Following the development of such a gene, bacteria may use plasmid exchange to transfer genetic information horizontally (between individuals). Multiresistant bacteria, also known as superbugs, carry several resistance genes. the reasons for it Transformation protocols can also be used to incorporate antibiotic resistance into a microorganism. This may be a good way to get artificial genes into a microorganism. Antibiotic tolerance is a product of natural selection in evolution. Antibiotic activity is a type of environmental pressure; bacteria that have developed a mutation that allows them to survive will continue to replicate. They will then pass this trait on to their children, resulting in a generation that is completely immune.

What is a mutagen?
A. A way to test for chromosomal mutations
B. A type of mutation involving chromosomes
C. An environmental agent that changes DNA
D. A mutation that is inherited from parents
The answer to the question is that Mutagen is an environmental agent that changes DNA.
Types of Mutagens:
Physical mutagens: Ionising radiation, such as X-rays, gamma rays, and alpha particles, is one example. UV radiations can also act as possible mutagens.Chemical mutagens: Mutagens include arsenic, nickel, and chromium. Some organic chemicals, such as benzene, are also mutagenic in nature.Biological mutagens: Transposonas and viruses are two examples of biological mutagens. Furthermore, some bacteria, such as Helicobacter pylori, have been linked to an increased risk of stomach cancer.Thus we can conclude that A mutagen is a physical or chemical substance that permanently alters genetic material in an organism, generally DNA, increasing the incidence of mutations over the natural background level.

6. Which of the following is NOT true of the excretory system? a. Kidneys remove waste from the blood b. Removes waste from sweating c. Excretes feces d. Excretes urine
Kidney waste from sweating is not true of the excretory system.
The correct answer is option B.
What does the excretory system do?The principal function of the urinary system is to maintain the volume and composition of body fluids within normal limits. One aspect of this function is to rid the body of waste products that accumulate as a result of cellular metabolism, and, because of this, it is sometimes referred to as the excretory system.
What are the parts of the excretory system and their functions?The primary excretory organs in the human body are the kidneys, ureters, and urinary bladder, involved with the creation and expulsion of urine. Through these organs, much of the nitrogenous waste of the body, especially urea, is expelled.
