Explanation:

Answer 2
Why do sunspots appear as dark spots on the surface of the Sun?

Answer: Sunspots are "dark" because they are cooler than their surroundings. ... Sunspots have a lighter outer section called the penumbra, and a darker central region named the umbra. Sunspots are caused by disturbances in the Sun's magnetic field welling up to the photosphere, the Sun's visible "surface".

Facts about the sun: The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy mainly as visible light, ultraviolet light, and infrared radiation. It is by far the most important source of energy for life on Earth.

Given what we know, we can confirm that using the using the Whitaker system, kingdoms are grouped based on cell structure and type, while the whoese-fox system groups major taxonomic groups into three major domains.

What is the Whitaker system?The Whitaker system is a classification system to order and organize the diverse biological life found on Earth. This is the most commonly-known system which orders organisms into the 5 kingdoms.

Biochemists developed a compound that they hypothesize will disrupt the ability of the cells to organize centrioles and microtubules. This compound is applied to a group of onion root tip

Answers

In order to serve as evidence that the hypothesis put forward by the Biochemists is true, they will have to observe that the onion cells stop multiplying and the roots do not grow.

The primary function of microtubules and centrioles in a cell (or at least one that they have in common) is their participation in cellular division, that is, mitosis and the formation of a cytoskeleton.

Without the formation of these structures, the cell will a cytoskeleton and the ability to divide. Therefore, we can confirm that evidence of this hypothesis would be for the cells to lack these functions.

Imagine that a woman has an oval-shaped head. Her father has the h h genotype. What proportion of head phenotypes do you expect to see in her children

Answers

The woman’s genotype is Hh because her father has the genotype hh. If the woman has children with a person who’s genotype is HH, you see 100% oval heads, you’d have genotype HH and Hh. If the woman has children with a person who is Hh, you expect 75% oval heads and 25% square heads with the genotypes HH, Hh, and hh. If she has children with some who is hh, you’d expect 50% oval, 50%square with genotype Hh and hh. To solve, use punnet squares!

Explain how one change in the Earth's biosphere can
cause changes in other Earth systems.

Answers

Answer:

interaction in the Earth's biosphere cause the change in other Earth system as the biosphere and atmosphere are dynamic, constantly reflecting these interaction. and Biosphere-Atmosphere Interactions focuses on the sources and sinks of greenhouse gases (GHGs), air pollutants, particulate matter, water, and energy between the Earth's surface and the atmosphere.

The Earth's biosphere is closely interconnected with other Earth systems, such as the hydrosphere (water), atmosphere (air), and geosphere (land). Changes in one part of the Earth's biosphere can have significant impacts on other Earth systems, and vice versa

What is a biosphere?

Biosphere means interactions with each other and their physical environment.

For example, changes in land use, such as deforestation or urbanization, can affect the Earth's water cycle and climate. Deforestation, for example, can lead to increased runoff and erosion, which can alter the availability and quality of water in an ecosystem. Deforestation can also lead to an increase in atmospheric carbon dioxide, as trees and other vegetation absorb and store carbon dioxide during photosynthesis. This can contribute to global warming and climate change.

Similarly, changes in the Earth's climate, such as an increase in temperature or a change in rainfall patterns, can affect the biosphere. Warmer temperatures can lead to the range expansion of certain species and the loss of habitat for others. Changes in rainfall patterns can affect the availability of water for plants and animals, which can lead to changes in the distribution and abundance of species in an ecosystem.

Answer:

Carbon is the backbone of life on Earth. We are made of carbon, we eat carbon, and our civilizations—our economies, our homes, our means of transport—are built on carbon. We need carbon, but that need is also entwined with one of the most serious problems facing us today: global climate change.

Photograph of a forest.

Photograph of a coal fire.

Carbon is both the foundation of all life on Earth, and the source of the majority of energy consumed by human civilization. [Photographs ©2007 MorBCN (top) and ©2009 sarahluv (lower).]

Forged in the heart of aging stars, carbon is the fourth most abundant element in the Universe. Most of Earth’s carbon—about 65,500 billion metric tons—is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels.

Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components. Any change in the cycle that shifts carbon out of one reservoir puts more carbon in the other reservoirs. Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth.

Draft diagram of the carbon cycle.

This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year. White numbers indicate stored carbon. (Diagram adapted from U.S. DOE, Biological and Environmental Research Information System.)

Over the long term, the carbon cycle seems to maintain a balance that prevents all of Earth’s carbon from entering the atmosphere (as is the case on Venus) or from being stored entirely in rocks. This balance helps keep Earth’s temperature relatively stable, like a thermostat.

This thermostat works over a few hundred thousand years, as part of the slow carbon cycle. This means that for shorter time periods—tens to a hundred thousand years—the temperature of Earth can vary. And, in fact, Earth swings between ice ages and warmer interglacial periods on these time scales. Parts of the carbon cycle may even amplify these short-term temperature changes.

Graph of oxygen isotope ratios in the deep ocean for the past 67 million years.

The global carbon cycle model describes the evolution of carbon mass in the mantle (Cm), the combined reservoir of ocean and atmosphere (Co+a), the continental crust (Cc), the ocean crust and floor (Cf), the kerogen (Cker), and the biosphere (Cbio).

What are the steps of carbon cycle?

Carbon on the dynamic planet can move from one of these realms to another as part of the carbon cycle.

Carbon is transferred from the atmosphere to plants.Carbon is transferred from plants to animals.Carbon is transferred from plants and animals to soils.Carbon is transferred from living things to the atmosphere.When fossil fuels are burned, carbon is released into the atmosphere.Carbon is transferred from the atmosphere to the oceans.

Thus, above-mentioned are the steps involved in a carbon cycle.

So, if you were to follow the arrow from the phytoplankton (or the producer), it would lead you to the zooplankton, krill, and cod. Since there are only one of these primary consumers as the choices, you would pick the only one available for the multiple choice, which would be krill :D

A gene is a segment of the DNA (deoxyribonucleic acid). DNA is the genetic material of the cell which contains the information for the development of different characteristics in an organism. Thus, the correct option is B.

What is a Gene?

A gene is the basic unit of heredity in an organism. It can also be defined as the molecular gene which is a sequence of nucleotides in the DNA molecule that is transcribed to produce a functional RNA which synthesizes a protein. There are two main types of molecular genes which include protein-coding genes and the noncoding genes.

Protein-coding genes or exons are the regions in the DNA which encodes for the synthesis of protein and the non-coding genes or introns are the segments of the DNA which does not code for any protein and thus are spliced in the post-transcriptional mechanism.

Therefore, the correct option is B.
