Answer:

D: an animal moves to a new population and mates

Explanation:

Gene flow, also known as gene migration, is the transfer of genetic material (DNA) from the population of a species to another population of the same species. Gene flow can be caused by migration of one member of a particular population that interbreeds in another population or due to aided transfer of gametes from one population to another, as in the case of cross-pollination.

Based on the above definition, an animal moving from its own population to a new population and mates there represents a scenario that causes gene flow.

In the first option, one flower of a population is pollinating another flower in the same population. This doesn't show gene flow because there is no transfer of genes (present in gametes) to a different population.

One would most likely find plants that are adapted to survive in hot, dry climates in a desert biome that is in option c, as the deserts are characterized by their hot, dry conditions and low annual rainfall.

Deserts are characterized by their hot, dry conditions and low annual rainfall. In order to survive in such an extreme environment, plants in the desert have evolved a variety of adaptations to help them conserve water and thrive in this harsh environment. One of the most important adaptations of desert plants is their ability to reduce water loss through transpiration. Transpiration is the process by which plants lose water through small pores on their leaves called stomata. In the desert, where water is scarce, plants have evolved a number of strategies to minimize water loss through transpiration.

As a result, plants adapted to survive in hot, dry climates are more likely to be found in option C's desert biome.

The Spinal Cord starts at the brain stem and goes to the tail bone.

Answer:

Stabilizing selection occurs when intermediate individuals are the most likely to survive.

Explanation:

Both because for example the birds with larger beaks could survive the drought and after 2 years stabilizing selection also occurs.

Answers:

Directional selection occurs when individuals with traits on one side of mean in their population survive or reproduce more than those on the other.

Hope it helps you.

Answer:

I believe both directional and stabilizing selection are operating in this example since only the large-beaked finches were able to survive the drought while the smallest-beaked finches disappeared. But also, we need to highlight after the second year stabilizing selection occurred because finches with large beak depth were the most likely to survive than those with smaller beaks, that is why that specific type of beak became more common.

Answer:

When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce, leveling off when the carrying capacity of the environment is reached, resulting in an S-shaped curve.

Explanation:

A population's per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity (K)

Answer:

Geologists can determine the age of an rock by studying it. However biologists study the evolution of fossils.

Explanation:

Geologists can determine the age of the Earth by studying the rocks and how long it took / takes them to form. Some similarities in their way of studying the Earth are the study of fossils. Both geologists and biologists study the evolution of fossils.

further information:

Geologists study Earth processes: Many processes such as landslides, earthquakes, floods, and volcanic eruptions can be hazardous to people. ... Geologists conduct studies that locate rocks that contain important metals, plan the mines that produce them and the methods used to remove the metals from the rocks.

Biologists study humans, plants, animals, and the environments in which they live. They may conduct their studies--human medical research, plant research, animal research, environmental system research--at the cellular level or the ecosystem level or anywhere in between. ... Biologists generally love what they do.

in conclusion, geologists are able to tell a rocks age by studying it but biologists can only study the age of fossils

hope this helped!

Answer:

In order to determine the age of rocks, Geologist takes advantage of basically two techniques that differ in their process and accuracy, these are relative dating and absolute dating.

Put simply, if a geologist says to be younger than his or her colleague, that is a relative dating. If a geologist says to be 28 years old, that is an absolute dating.

Relative dating relies on a set of principles, formulated by geologists that can be applied on different types of rocks (sedimentary or volcanic) on the Earth's surface to determine the relative ages of geological events kept in rocks as a record of such events. Together with these principles, geologist uses the arrangement of rock layers to estimate the relative age of rocks with it. This process is called stratigraphy, and a branch of it, called sequenced stratigraphy seeks to determine the order or sequence in time in which rocks were laid in the available space –or accommodation in geologist terms-  The principles stated before are Superposition, Faunal succession, Crosscutting relationships, and Inclusions.

It is common that geologists come across gaps in the geologic record, for which they use “index fossils” to define and identify geologic periods, which helps relatively date rocks ages.

By the other hand, absolute dating puts a specific number on the age of rocks (say 25 million years sold i.e.) with the use of more precise techniques. In this case, this method provides chronologically organized estimates of the age of geological materials related to fossils. Since elements such as calcium and potassium decay in their radioactivity, this phenomenon is used by geologists as a clock to determine the age at which rocks or fossils were formed. Knowing this, geologist design procedures called radiometric dating methods to date ancient events with the use of elements radioactivity decay.

A leaky heart valve might go unnoticed. Or it could cause health problems that could be either minor or serious. How serious a leaky heart valve is depends on how much it interferes with normal blood flow through the heart. Treatments include medicines, surgical repair, or surgical replacement of the leaky valve. Observation over time for changes is the most common approach to a leaky heart valve.

Answer:

Answer B. Endosymbiosis

Explanation:

Early protists were first eukaryotic organisms and had several membrane bound organelles. The anaerobic protists evolved by acquiring purple bacteria. The purple bacteria have the ability to carry out aerobic cellular respiration. The endosymbiont transformed into mitochondria in due course of evolution. Similarly, the photosynthesizing protists were evolved by endosymbiosis of cyanobacteria which in turn was transformed into chloroplast during further evolution.

Answer:

With less water flowing into the lake, the water temperature increases. Some species are unable to survive in the warmer water.

Explanation:

Biodiversity of a lake is dependent on the flows from rivers. The health of the biota of the lake would be greatly affected when there is reduced flow of water from the river as a result of diversion into dams for agriculture purpose.

The major impact reduced water flow will have on the biota of the lake is that many species that cannot tolerate draught as a result of increase in water temperature caused by reduced flow of water, would eventually become extinct. The biota of the lake would diminish or decline.
