Is it the male or female that determines the sex of a zygote? Based on chromosomes, how do we know this to be true

Answers

Answer 1

Answer:

The male

Explanation:

A female always gives one X chromosome, a male can give either an X or a Y. If a zygote receives an X from its father and another X from its mother, it will be female. If a zygote receives a Y from its father and an X from its mother it will be male. Because the mother only has one option of chromosome to give, her chromosomes will not effect the gender of the zygote.

Which process most likely enabled the formation of the early protists? A. photosynthesis B. endosymbiosis C. conjugation D. binary fission

Answers

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.

Interpret: Directional selection occurs when individuals at one end of a range are more likely to survive than intermediate individuals or individuals at the opposite end of the range. Stabilizing selection occurs when intermediate individuals are the most likely to survive.


Is directional selection, stabilizing selection, or both operating in this example? Explain.




Think and discuss: Evolution is the process by which populations of organisms can change over time. How is directional selection related to evolution?

Answers

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.

WILL GIVE BRAINLIEST!!!!What are the similarities and differences in the way geologists and biologists approximate the age of the earth? Justify your response in two or more complete sentences.

Answers

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.

Answers

The answer would be Desert (c) as it has the hottest climate and is most likely the dryest

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.

What is a desert?

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.

a population is made up of different communities in an area true or false

Answers

Answer:

True.

Explanation:

A population is made up of different communities in an area. This statement is false. A community is made up of different populations.

What is a community?

A community consists of different species living in a particular area. An example is that a community may consist of the tiger population, the elephant population, the deer population, etc.

A population is a group of similar individuals present in a particular area, for example, a population of elephants, a population of tigers, etc. In the population, all the organisms belong to a single species.

Different populations interact with each other to make a community. Different communities make up an ecosystem. The ecosystem consists of both biotic and abiotic components. The biotic component includes all living animals and plants. Abiotic components include all the non-living substances such as air, water, soil, etc.

Hence, the community is made up of various populations, but the population is not made up of communities. So the given statement is false.

A river flows into a lake. A community builds a dam to divert the river for crop irrigation use before it reaches the lake. Which describes a way in which biodiversity in the lake will be directly affected by this change?
Select one:

The size of the lake will increase, attracting more organisms who rely on it as a water source.

Nutrient levels in the lake will increase, encouraging the growth of new plants.

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

Diverting the river will introduce new, invasive species into the lake.

Answers

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.
