Which factors involving the activities of people are a threat to biodiversity?
Answer:
Explanation:
Overexploitation of a species. Take elephants for example. Hunters hunt them down for ivory. Say that there was a disease going around elephants, that is incredibly deadly. Take Bobby the elephant. Bobby the elephant is one of the few that has natural immunity to the virus, and if he were to reproduce he could help save the elephant population. If Bobby was hunted down before he reproduces, the population of elephants are put in danger. Also killing a large portion of a species will make it so that the animals in that species have limited mating partners, which can restrict biodiversity
Explain how the diagram below shows the evolution of bacteria? (60 POINTS)
Explanation:
Bacterial evolution refers to the heritable genetic changes that a bacterium accumulates during its life time, which can arise from adaptations in response to environmental changes or the immune response of the host. Because of their short generation times and large population sizes, bacteria can evolve rapidly.
In what cell cycle checkpoint CDK is present?
Where is the gas-exchange surface in the bird respiratory system, i.e. where does oxygen enter the blood and carbon dioxide leave the blood
Answer:
the lungs
Explanation:
The avian respiratory system consists of three sets of organs that perform respiration: lungs (where gas exchange occurs), anterior air sacs and posterior air sacs. The lungs have static structures with surfaces that enable gas exchange, and air sacs that enable the unidirectional flow of air through the lungs. Birds have a very efficient respiratory system that obtains oxygen when they breathe in and breathe out. The inhaled air reaches the primary bronchus where enters to the lungs for gas exchange and also fills the air sacs.
(Q029) Which of the following statements is FALSE? Group of answer choices Formins promote the formation of unbranched actin filaments. Actin filaments are usually excluded from the cell cortex. Integrins are transmembrane proteins that can bind to the extracellular matrix. ARPs can promote the formation of branched actin filaments.
Answer:
- Actin filaments are usually excluded from the cell cortex
Explanation:
In eukaryotic cells, actin proteins polymerize in order to form filaments. These actin filaments can be localized beneath the plasma membrane, where they form a network that helps to provide mechanical support. This network localized on the inner face of the plasma membrane is called 'cell cortex', which is a specialized structure that is attached to the cell membrane by Ezrin, Radixin and Moesin (ERM) proteins. The cell cortex plays key roles by controlling the cell shape, cell morphogenesis and membrane behavior.
The statement "Actin filaments are usually excluded from the cell cortex" is false.
In point of fact, actin filaments are most frequently discovered in the cell cortex, which is a highly specialised region that is located close to the plasma membrane.
Actin filaments are abundant in the cell cortex, where they serve as a source of structural support and contribute significantly to the processes of cell shape maintenance, cell adhesion, and cell migration. Actin filaments play a pivotal part in these cellular functions.

Which of the following statements is true?
A. The karyotypes for a male human and a female human will look exactly the same.
B. The number of chromosomes in all organisms is the same.
C. Sometimes, a single gene can influence many traits.
D. There are more chromosomes in a cell than there are genes.
Answer:
the answer is C
Explanation:
Sometimes, a single gene can influence many traits in an organism. This is possible due to gene interactions. Thus, the correct option is C.
What is Gene interaction?Genetic interaction is the set of functional association between different genes in an organism. Genetic interactions are the relationship is called as epistasis. Epistasis is the interaction of non-allelic genes where the effect of one gene in an organism is masked by another gene to result either in the suppression of the effect of that gene or they both combine to produce a new trait or character.
In epistasis, the gene which masks another gene is called as epistatic gene, and the gene whose expression is being masked is termed as hypostatic gene. Epistasis is also referred to as the inter-genic or inter-allelic gene interaction.
Therefore, the correct option is C.

Why are recessive traits not seen even though they are present in the alleles?
Answer:
Because if the dominant trait (D) is present, it will in a way, overpower the recessive trait (r), and show the dominantly present trait physically but in the alleles, there might be blue in there also but be overpowered for ex: dominant brown eyes with a blue recessive trait so most likey if you have brown since it takes over

In Holstein cattle the spotting of the coat is due to a recessive gene, while a solid-colored coat is dominant. Two heterozygous solid animals are crossed. What would be the expected genotypes and phenotypes of the offspring?
Answer:
In Holstein cattle when two heterozygous animals are crossed for the characteristic coat color, the offspring will be individuals with solid coat and spotted coat in a 3:1 ratio.
Explanation:
Since in Holstein cattle the solid color coat is dominant (S), and the spotted coat is recessive (s), each heterozygous individual has the genotype Ss.
The result of crossing two individuals of Holstein cattle heterozygous can be seen in Punnet's Square:
Ss X Ss
Alleles S s
S SS Ss
s Ss ss
Genotypes
Ss 50%SS 25%ss 25%Ratio of genotypes SS:Ss:ss is 3:1:1
Phenotypes
Individuals with solid color coat 75% (50% Ss and 25% SS). Individuals with a spotted coat 25%.Ratio solid color:spotted color 3:1
why is the cell membrane called the fluid mosaic model? quick if you can please
Answer:
The fluid mosaic model of the cell membrane is how scientists describe what the cell membrane looks and functions like, because it is made up of a bunch of different molecules that are distributed across the membrane. ... The movement of the mosaic of molecules makes it impossible to form a completely impenetrable barrier.
Explanation:
The cell membrane is called the fluid mosaic model because proteins are arranged as a mosaic of particles that can penetrate inwards and even completely pass through the bilayer.
According to this fluid mosaic model, membranes consist of a lipid bilayer (essentially a double layer of phospholipids) in which various proteins are embedded.
The lipid bilayer is the base of the membrane, proteins are normally found "dissolved" in the lipid bilayer, they act as mediators or facilitators of almost all the functions of the membrane, either by transporting specific molecules.It also highlights that the membranes are fluid, dynamic and their components mobile, a very important characteristic that allows the existence of transitory interactions.Finally, this model of the membrane structure proposes that the arrangement of its components is asymmetric and they can have numerous associated carbohydrates.Therefore, we can conclude that the cell membrane is called the fluid mosaic model because proteins are arranged as a mosaic of particles that can penetrate inwards and even completely pass through the bilayer..

Water vapor inside magma increases its explosiveness.
true or fasle
Answer: True.
Explanation: When the water vapor bubbles try to rise they are impeded by the linkage of silica chains in the magma and can rise only slowly. The rapid change in confining pressure as the magma body rises to the surface causes the dissolved water vapor bubbles to expand and escape explosively.

an increase in nitrates from animal wastes
d
Answer:
The correct answer is - a decrease in nitrogen compounds available to organisms.
Explanation:
Nitrogen fixation is the process that involves the atmospheric nitrogen and converts into a nitrogen compound that can easily be consumed by the organism as nitrogen is one of an essential part of life.
Nitrogen fixation is carried out by the microorganism like nitrogen-fixing bacteria like azotobactor. If these bacteria were destroyed then there will be a decrease in the nitrogen compounds that are consumed by the organism as there is no more nitrogen fixation takes place.
What are the two general types of cells in the human body?

Answer: The options are not given, here are the options.
.a.prophase
b.prometaphase
c.metaphase
d.anaphase
e.telophase
The correct option is C.
Metaphase.
Explanation:
It is metaphase because during metaphase, the chromosomes lined up together and the two sister chromatids join to a particular spindle fiber. The microtubules them bring the sister together chromatids from the opposite spindle poles. The kinetochore microtubules capture the sister chromatids back and forth til they are able to form alignment along the equator of the cell which is called the equatorial plane.
