Penicillin-binding protein 2a, encoded by the medA gene, isn’t affected by beta-lactam antibiotics.
True
False
Answer:
The correct answer is - false.
Explanation:
Penicillin-binding protein 2a or PBPs are protein produced by bacteria that binds with the β-lactam antibiotics such as penicillin. They play role in the cell wall synthesis of bacteria by producing peptidoglycan by catalyzing the reaction.
β-Lactam antibiotics bind with the PBPs and cause the disruption to peptidoglycan cross-linking in the biosynthesis of the cell wall and ultimately lysis of bacteria takes place and cell death.

Sex Linked Inheritance
Why are women often carriers of X-linked traits but rarely affected by them?
Answer:
See the answer below
Explanation:
Women are often carriers of X-linked traits but are rarely affected by the trait because they have two X chromosomes and the two have to carry the X-linked allele in order for them to be phenotypically affected, especially if the trait is a recessive one.
Unlike men that are XY and only require one X-linked allele in order to be affected for X-linked recessive traits, women need two alleles - one on each chromosome - in order to be affected. One of the X chromosomes of a woman usually comes from the woman's father and the other one from her mother. In order to be affected, a woman must inherit an affected chromosome from her father and her mother respectively, thereby reducing the probability of having the trait.
The X chromosome of a man usually comes from his mother. Hence, a man only needs to inherit an affected chromosome from his carrier mother to be affected for the trait, thereby increasing the probability of having the trait when compared to a woman.
This is not the case for X-linked dominant traits where both men and women have an equal chance of being affected.
Women carry two XX chromosomes in their cells. They carry the X chromosome but rarely gets affected by the trait because to be phenotypically affected they should carry X linked disease trait on both the X chromosomes.
Especially in the case when the trait is recessive then they should have two XX chromosomes which are linked to traits.
In the male, they have one X and one Y chromosome so they acquire an X chromosome and gets affected by it.
In male presence of one X chromosome from the carrier mother is enough to pass the trait. While in females to have X linked recessive trait they should have two alleles.
The woman does not get affected as one chromosome comes from the father and the other from the mother so to be affected the woman must acquire genes with traits from both parents.
Therefore, women are often carriers but are rarely affected by them.

How can we explain why there is so much biodiversity on Earth today? How did it come about?
Answer:
How can we explain why there is so much diversity of life on Earth today?
There are several key reasons for high biodiversity in tropical ecosystems. High NPP directly contributes to α-diversity by supporting more species with minimum viable populations, whereas enlarged populations of each organism increase overall mutation frequency and hence intraspecific genetic variation.

Why do waves move faster at higher temperatures and in a solid phase?
O There is more energy and the particles are farther apart.
O There is less energy and the particles are closer together.
O There is less energy and the particles are farther apart.
There is more energy and the particles are closer together.
Answer:
B
Explanation:I took the test if u need help follow me
Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.
What is meant by intermolecular force ?Intermolecular force is defined as the force of attraction experienced between the neighboring molecules in the same state.
Here,
During higher temperature and when in a solid phase, the waves exhibit movements very faster than in other phases.
This is because, when the temperature of the system is increased, the energy of the molecules in the system will be increased to a higher level. This energy formation is in the form of kinetic energy of the molecules.
Molecules in the solid phase have a greater intermolecular force of attraction with their neighboring molecules. Therefore, the molecules in the system will be more closer to each other.
As the kinetic energy of the molecules in the system increases, the molecules will start vibrating. These vibrating molecules induces the vibration to their neighboring particles, since they are closer together.
As a result, more and more highly energetic molecules are set to vibrate, which causes the wave to move faster in the system.
Hence,
Waves move faster in higher temperature and in solid phase because there is more energy and the particles are closer together.

Which plate boundary and movement commonly create volcanoes that can result in the development of habitable islands? Explain how islands can be created by plate tectonics. Plz hurry up I need this done in five min
The plate boundary and movement that commonly create volcanoes that can result in the development of the habitable island are convergent plates.
What are volcanoes?Volcanoes are the eruption of lava or magma from the earth's crust. This happens due to earthquakes. Due to the earthquake, the plate's tectonic collide with each other.
When the tectonic plates collide with each other three types of formation happen, both plates move upwards both played move away from each other or one plate goes under the other plate.
As volcanoes erupt, layers of lava are built up that could someday break the surface of the water. An island is created when the tops of the volcanoes rise above the surface of the ocean.
Thus, convergent plates are those that frequently result in volcanoes and plate boundary movement that can lead to the establishment of a habitable island.

In three sentences or fewer, explain the difference between using geothermal energy to generate electricity and using the geothermal gradient to heat your home with an underground heat pump.
Answer:Tapping of geothermal energy to produce electricity is done on a larger scale compared to the tapping of the geothermal gradient using a geothermal heat pump. Harnessing geothermal energy is also reliant on geological conditions such as in the area of convection boundaries while geothermal gradient can be harnessed virtually anywhere on the earth surface.
B. Energy from sources such as geothermal or from solar is used to spin the blades of the turbine. The turbine then powers a generator, which produces electricity" is the best answer but one of the most common energy inputs is wind, not solar.
circulatory system summary
Answer:
The circulatory system or vascular system is an organ system that helps in the transport of the blood from and to the heart. The blood transport also takes oxygen, nutrients, hormones, and other components from the heart to the various part of the brain with the help of the arteries and carry waste such as carbon dioxide to the heart in veins.
The oxygenated blood enters in the left atrium and moves to the left ventricle to the aorta and starts its journey to the body whereas deoxygenated blood enters in the right upper chamber or right atrium of the heart and pump to the right lower chamber and to the lungs to carry the oxygen again. This process is a continuous process.
