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.

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

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.
Why is it best to have a resting heart rate below 70 beats per minute?
Answer:
While the average adult's resting heart rate should range between 60 and 100 bpm, anything over 90 bpm is considered high. Generally speaking, lower heart rates are considered better as it means that the heart muscle doesn't have to work as hard to keep a strong, steady rhythm.
help is appreciated (: (biology) thank you
Answer:
A
Explanation:
Nuclear division occurs during prophase, which is when chromosomes condense and become visible, spindle fibers emerge from centrosomes, and centrosomes move toward opposite poles. We see this occur in process A
identify the values and describe the attitudes that have contributed to pollution problems like those at herculaneum. how would you feel if you lived in herculaneum
Answer:
Herculaneum was an ancient town in Italy. Herculaneum has faced a lot of problems related to pollution that are contributed by humans.
During the eruption, the bones of hundreds of victims were left in the beach sites in the open air and the disintegration of dead bodies caused a lot of pollution in the area. Lead contamination is a common issue in Herculaneum that is creating environmental health hazards such as pollution. Plants and vegetation are rarely supported in Herculaneum people that increases the effects of pollution.
If i would have lived in Herculaneum, I would have felt suffocated in such an environment where there is a lot of pollution and I would try to plant some trees or vegetation nearby to support environmental health.

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.

During heavy exercise, the blood's volume flow rate is 5-10 times higher than when the body is at rest. Discuss different possible ways that a body can accomplish this
Answer: Two possible ways are aerobic respiration and anaerobic respiration.
Explanation:
Aerobic respiration: During aerobic respiration, the muscles of the body during vigorous exercise experience lack of oxygen as a result heart pumps faster to avail the necessary blood volume of oxygenated blood to all the muscles.
Anaerobic respiration: In the absence of oxygen the glucose stored in muscles is converted into lactic acid and this process avails energy for performing work but also causes cramps in muscles.

(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.
