Answer:
The color of a dog's fur with the genes aabb would be yellow. So, in other words, Option A is correct.
Hope this helped :D Happy holidays! :D
Epistasis is the effect or character appear due to the interaction between genes. Here, the alleles responsible for the color of dog's fur show epistasis and the progeny with (aabb) genotype will show white colored fur. Thus, the correct option is D.
What is Epistasis?
Epistasis is also known as gene masking, where the expression of one gene is modified or masked or suppressed by the expression of another gene or more other genes. In this, more than one gene controls a specific character such as fur color, etc.
Epistasis is of different types such as dominant epistasis, recessive epistasis depending upon the effect of genes.
Here, the progenies with AABB genotype show black colored fur, the progeny with Aabb show brown colored fur, the progeny with genotype aaBB show yellow colored fur, and therefore, the progeny with genotype aabb i.e., both the recessive genes will show white colored dog fur.
Therefore, the correct option is D.

Introduction
In order for organisms to grow, cells have two options: they must either replicate themselves to create more cells, or the cells themselves must expand in volume. In humans, tissues such as the skin and blood contain cells that are actively dividing, whilst other tissues such as fat contain cells that expand (good if you need energy for winter, bad if you are trying to fit into some expensive jeans). Other cells, such as neurons, will never divide again once they are terminally differentiated; they are post-mitotic.
In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for sexual reproduction, where their genetic content will be made whole again by the process of fertilisation? This choice is the choice between mitosis and meiosis.
Difference Between Mitosis and Meiosis
This article will explore the characteristics of both kinds of cell division, shining a light on how they are similar and in which aspects they are crucially distinct. We will also explore the research into these processes and how cell division might go awry to cause disease states such as cancer and Down’s Syndrome.
Mitosis vs. Meiosis: Overview and commonly asked questions
Mitosis
Meiosis
What is the purpose of this process?
In a unicellular organism, the purpose of mitosis is to proliferate asa species. In a multicellular organism, the purpose can be to grow during development, or to repair or regenerate
adamaged tissue, for example.
To create gametes with only one copy of the organism’s genetic information, in preparation for sexual reproduction. Various steps in meiosis create opportunity for genetic diversity in the daughter cells. This is the raw substrate for evolution.
What is the outcome of this process?
Two diploid cells with identical genetic information.
Four haploid cells with different genetic information.
Which organisms perform this process?
Mitosis is performed by unicellular and multicellular eukaryotes.Bacteria have their own version of mitosis called “binary fission”.This is distinct from meiosis as bacteria typically have one circular chromosome,which is not contained within a nucleus, like eukaryotic chromosomes.
Only organisms which perform sexual reproduction. Archaeaand bacteria do not do this, so it might be tempting to think that unicellularorganisms do not sexually reproduce. However, there are exceptions; buddingyeast will form haploid spores under nutritional deprivation.
How long does this process take?
Mitosis is usually shorter than meiosis. The process can take over 10 hours for mammalian cells in culture [2], budding yeast can take ~80 minutes to complete a cell cycle [3], whilst bacteria can divide every 20 minutes.
Meiosis has various timescales in different organisms, which can be affected by several factors including temperature and environment of the organism, and the amount of nuclear DNA. The process lasts 6 hours in yeast but can last more than 40 years in human females, due to a developmental hold at prophase I, until ovulation. Other examples are 1-2 days in male fruit flies and ~ 24 days in human males. [1]
What is an example of a disease caused by an error in this process?
Uncontrolled mitosis occurs in cancer, where either genes that stop cell division (tumour suppressors) are switched off, or genes that encourage cell division (oncogenes) are overactive.
Errors in meiosis can lead to the wrong number of chromosomes ending up in germ cells, this is called aneuploidy. This can trigger miscarriage, but is occasionally tolerated. One example is Down’s syndrome, caused by trisomy 21. Another example is Klinefelter syndrome, where XY males have an additional X chromosome.
Summary
Meiosis and mitosis both have a prophase, metaphase, anaphase, telophase and cytokinesis.
In meiosis, prophase, metaphase, anaphase and telophase occur twice. The first round of division is special, but the second round is more like mitosis.
In mitosis, prophase, metaphase, anaphase and telophase occur once.
Prophase
Chromosomes condense and the centrosomes begin to form an early spindle.
Meiotic prophase I is much longer that mitotic prophase.
During prophase I homologous chromosomes make contacts with each other called chiasmata and “crossing over” occurs. This is where chromosomes exchange sections of DNA. This is important for generating genetic diversity but is also crucial mechanically to hold homologous chromosomes together.
Mitotic prophase is much shorter that meiotic prophase I.
There is no crossing over in mitosis.

Answer:
Cells have to do a few things, first they either have to replicate themselves, or they must expand. In our human bodies our cells do both. Replicating when we break skin, and expanding for the winter. Some cells never divide though. But cells also have to choose is they will make identical copies, or 4 half copies. Half copies have a sexual re-productions. And this is the choice of mitosis and meiosis.

which type of organism can use photosynthesis to make food
Answers
Answer:Plants
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 1). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).
Explanation:
Answer:
All plants with green leaves, from the tiniest mosses to towering fir trees, synthesize, or create, their own food through photosynthesis. Algae, phytoplankton, and some bacteria also perform photosynthesis. Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis.

Energy conversions are common in nature. Much of the energy from the breakdown of the hummingbird body weight is released as heat energy back into the hummingbird's environment.
According to the laws of thermodynamics, energy is neither created nor destroyed but is converted from one form to another. Living things take in food to release energy to carry out their daily activities.
Sometimes, energy is obtained from the breakdown of body fat. In either case, much of this energy is released back into the environment as heat energy.

What is consciousness ?
Answers
Answer:
consciousness is the difference between a rock and a hard place to stay in 6
Consciousness is a complex and multifaceted phenomenon that refers to our subjective Consciousness of the world and ourselves.
Consciousness encompasses our awareness, perception, thoughts, emotions, and the sense of self.
Some theories of Consciousness:
1. Dualism: According to dualism, the mind or consciousness exists independently of the brain and can potentially survive even after the death of the body.
2. Materialism: Also known as physicalism. According to materialism, consciousness is an emergent property of the complex interactions among neurons, neural networks, and brain structures.
3. Integrated Information Theory (IIT): According to IIT, consciousness emerges when information is both highly integrated (information is interconnected) and highly differentiated (information is diverse).
4. Global Workspace Theory (GWT): The global workspace is a dynamic neural network that allows information to be shared across different cognitive processes and enables access to conscious awareness.
5. Phenomenal consciousness vs. Access consciousness: Phenomenal consciousness refers to what it feels like to experience something, while access consciousness pertains to the ability to use that experience for various cognitive tasks.
Thus, the term "consciousness" refers to our individualized perception of the outside world and of ourselves.

What are plant hormones?
Almost every element of plant growth and reaction to its environment is regulated by plant hormones. Numerous plant hormones play important roles in the interactions between plants and helpful microorganisms because they are active at extremely low concentrations and have precise spatial control of synthesis and response.
The "The Role of Plant Hormones in Plant-Microbe Symbioses" special issue offers fresh information on the functions of hormones produced from both the plant and the microbial partner in symbiosis establishment and communication. This includes the close symbioses that the majority of terrestrial plants have with arbuscular mycorrhizal (AM) fungi, as well as the more recently acquired nodulation—symbioses between a select group of plants in the fabid clade and nitrogen-fixing bacteria.
The articles in this special issue also look at how hormones affect how plants interact with ectomycorrhizae, endophytic bacteria, and fungi, and helpful microorganisms that stick to the surfaces of the leaves and roots. Many hormones can interact with one another in addition to acting directly to regulate the growth of these symbioses, and these intricate networks are just beginning to emerge.
Therefore, various plant hormones are used commercially.

Answers
Answer:
As you have learned, the process of mechanical digestion is relatively simple. It involves the physical breakdown of food but does not alter its chemical makeup. Chemical digestion, on the other hand, is a complex process that reduces food into its chemical building blocks, which are then absorbed to nourish the cells of the body. In this section, you will look more closely at the processes of chemical digestion and absorption.
