explain how the adaptation to reproduce quickly is beneficial in bacteria's ability to
develop resistance to antibiotics
Answer:
Antibiotics save lives but any time antibiotics are used, they can cause side effects and lead to antibiotic resistance.
Since the 1940s, antibiotics have greatly reduced illness and death from infectious diseases. However, as we use the drugs, germs develop defense strategies against them. This makes the drugs less effective.
The population of white pines on his land in 2015 was 40. After last weekend the population is 155. Find the growth rate.
Answer:
287.5%
Explanation:
Initial = 40
Recent = 155
Growth rate = ( recent - initial )÷ initial ×100/1
=( 155-40/40) × 100/1
= 115/40×100/1
= 2.875×100/1
= 287.5%
The rate of growth is 287.5%

Which is the most likely result if the Ubx gene was activated either before or after it normally is activated in the sequence of Hox gene expression?
A. The insect develops slightly shorter or longer abdominal legs.
B. The insect develops normal body parts at either a slower or more rapid rate.
C. The insect develops normal body parts but in an altered time sequence.
D. The insect develops legs in other parts of its body.
Answer:
D. The insect develops legs in other parts of its body.
Explanation:
HOX genes, also known as homeotic genes, are evolutionarily conserved genes (containing homeobox sequences) that encode master regulators of embryonic development in animals. Hox genes modulate the body plan of an embryo along the head-tail axis. In general, these genes are arranged in the same order as they are transcriptionally expressed along the anteroposterior body axis. Moreover, Ultrabithorax (Ubx) is a Hox gene that is responsible for the proper development of the third thoracic segment in insects. In Drosophila, it has been shown that different segments of the leg regulate their size in response to Ubx expression.
Which statement best describes the relationship between ocean co2 and ph
Acidity rises and pH falls as carbon dioxide levels rise. The correct option is C.
What is ocean pH?A change in the characteristics of ocean water known as ocean acidification may be detrimental to plants and animals.
Scientists have noticed that the ocean's acidity is rising as a result of the water's absorption of atmospheric carbon dioxide.
Ocean acidification is the decrease in the ocean's pH level. The average pH of the ocean's surface fell from about 8.25 to 8.14 between 1751 and 2021.
Ocean water is more basic than drinking water because it is resistant to pH fluctuations due to the presence of various weak acids and their corresponding bases, or buffers.
The ocean is regarded as having a pH that is slightly alkaline. Acidity and pH both drop when carbon dioxide levels rise.
Thus, the correct option is C.

In 1989, a tanker carrying oil struck a reef and spilled 11 million gallons of oil in an
Alaskan bay. The oil not only spilled into the harbor, but also washed up on the
shoreline. The spill killed millions of fish, birds that lived on the shore, sea otters,
porpoises, seal lions and many whales. Every form of life in the area was affected.
Scientists have carefully studied the area and its species since the initial spill to
determine both short-term and long-term effects.
Which of the following was affected the least by this catastrophic event? A: Plants along the shoreline B: Fishermen in the area C: Migratory sea birds D: Crustaceans that lived on the bottom of the bay
Answer:
The answer is C: Migratory sea birds.
Explanation:
Sea birds that are migrating would not only just fly above the spill and nestle on the trees, but they could eat crabs and other animals that scurry around on the shore as a food source due to the death of their primary source of food, fish.

The Sun is at the center.
The Earth was at a point slightly offset from the center.
The stars are attached to the outermost sphere.
Earth is at the center.
Each planet is attached to a crystalline sphere.
Answer:
The Earth is at the center
Explanation:
Aristotle was the first to believe the earth was round but he still thought everything revolved around the earth.
Aristotle's geocentric model of the solar system was based on the belief that the planet moves around the earth at the same speed.
One peculiar thing about this model was that the earth was said to be at the centre, which is why it is described as the geocentric model.
Some characteristics of this model include:

Texto donde se desarrolle la definicion de seleccion natural. Además, empleem los siguientes terminos: Variabilidad, mecanismo selectivo y Darwin.
Answer:
la selección natural es el mecanismo principal por el cual la evolución ocurre
Explanation:
Charles Darwin fue un naturalista inglés que propuso la teoría de la evolución o 'descendencia con modificación' mediante el mecanismo de selección natural. Acorde a esta teoría, la selección natural se define como el mecanismo selectivo de reproducción diferencial de los individuos mejor adaptados a su ambiente. La variabilidad es el la materia prima sobre la cual la selección natural actúa, seleccionado aquellos individuos que presentan combinaciones fenotípicas y genotípicas más adaptadas para sobrevivir en un ambiente en particular. Los individuos de una población que son 'superiores adaptativamente' poseen más chances de sobrevivir y reproducirse, y por lo tanto tienen también más probabilidades de transmitir sus genes a la siguiente generación.

2. Which explanation for the increase in genetic diversity of this red panda population is supported by this data?
(1 point)
Red pandas in this population have encountered new predators due to the increase in deforested land, and this new predation pressure has selected for different adaptations.
Red pandas in this population have increased the number of cubs birthed by each mother every year, and this increase in population has resulted in more genetic diversity.
Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.
Red pandas in this population have started eating a new diet due to the increase in deforested land, and the new dietary conditions have selected for different adaptations.
5. Which of the following scenarios would reduce the number of inheritable traits in a population, causing the individuals in that population to remain very similar to one another?(1 point)
A swamp that is being drained in order to build houses.
A forest that is being converted into farmland.
A lake that is drying up due to shifts in river flow.
A desert that has existed for millennia.
Answer:
2. C - Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.
5. D - A desert that has existed for millennia.
Explanation:
2. Predation (A) and fertility (B) are easy scratch-off answers -- given the situation of deforestation, these factors will not influence genetic diversity. Although eating patterns can lead to new adaptations, the best answer is C because it results directly from the issue at hand: deforestation.
5. To limit the amount of population diversity, you would have to maintain the same environment as much as possible. In other words, migration and isolation lead to the creation of new species per Darwin's theory of Natural Selection. For that reason, the only plausible answer here is D.

Which type of human population is characterized by the lag phase, being able to raise crops and domesticated animals, but having over farming methods that lead to soil eorion and food shortages?
Answer:
Rural population.
Explanation:
The rural population of humans is characterized by the lag phase because they are linked with farming of crops and domesticated animals. This population is responsible for the soil erosion and food shortages over the country because they are the producers of everything for the food industry. Due to farming methods, soil erosion occurs that leads to the depletion of nutritive part of the soil that causes less productivity of the crop and as a result food shortage occur.

When pure black hamsters were mated with pure white hamsters, all of the offspring were black. The trait for whiteness would best be described as?
Answer:
Recessive
Explanation:
All of the offsrping were black so that means black was the dominant gene and white was the recessive
At the time when the pure black hamsters were mated so here, the whiteness trait should be called the recessive.
What is recessive?It refers to the allele type that should not be manifested in an individual till both individual copies of the gene should include the particular genotype.
And, all the offspring should be considered as black so here black treated as the dominant gene and white should be considered as the recessive
Hence, the whiteness trait should be called recessive.

The fact that choanoflagellates and collar cells of sponges resemble each other supports the inference that ________. Group of answer choices choanoflagellates are animals choanoflagellates are more closely related to sponges than they are to protists choanoflagellates and sponges evolved similar cell structures through convergent evolution choanoflagellates and sponges are sister groups
Answer:
choanoflagellates and sponges are sister groups
Explanation:
The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.

4.What is the carrying capacity of an ecosystem?
5.What kind of factors do you think can change a carrying capacity?
6. Compare artificial selection to natural selection?
7. How do environment factors and genetic factors affect natural selection?
Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. 2. Adaptedness is the state of being adapted: the degree to which an organism is able to live and reproduce in a given set of habitats.
On the western peninsula, the changing climate means different weather is turning sheets of snow and ice into a land of rain and mud. Older penguins are equipped with waterproof layers of feathers allowing them to move swiftly in the water, and also allowing them to stay warm on land.

Carrying capacity can be defined as a species' average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.
6.Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.
