The Texel sheep is a breed of sheep that has gone through selective breeding for both food and wool production. The wool is of medium thickness without black fibers and commonly used in crafts. The sheep are bred for their large muscle size. The increase in muscle size has led to increased size in offspring.
How has this biotechnology harmed the Texel sheep?
Answer:
loss of genetic diversity
Explanation:
Artificial selection, also known as selective breeding, refers to the identification by humans of desirable phenotypic features (traits) in plants and animals and the subsequent breeding procedures to enhance and perpetuate these traits in offspring. As a consequence of artificial selection, future generations of selectively bred animals/plants will share favorable gene variants (alleles), thereby genetic diversity will decrease in the population. This reduction in the gene pool will affect genetic progress and consequently also breeding programs in the future.

write short notes on the following. (a) Cytoplasm (b) Nucleus of a cell
Answer:
Explanation:
Cytoplasm Structure Cell organelles are various structures existing inside cells. All these structures are distinct and perform specific functions. Cells have three main elements i.e., plasma membrane, and cytoplasm and the nucleus. The plasma membrane or cell membrane is a bi-lipid membranous layer, parting the cell organelles from its outside environment and from the different cells. It is the external covering of a cell where all different parts, including cytoplasm and nucleus, are enclosed. Next, is the nucleus, one of the biggest organelle. They have exclusive control of a cell. Lastly, the cytoplasm is a jelly-like material in which the cell organelles are implanted. The cytoplasm is an essential component of the cell. It is a semi-liquid jelly-like material, which joins the nucleus and the cell membrane. In the cell, the cytoplasm is embedded, while other cell organelles such as endoplasmic reticulum, mitochondria, ribosomes, vacuoles, etc. are all suspended within it. It can easily be examined under a microscope through the staining technique. Functionally, it is the site for several chemical reactions within a cell. Most of the cellular metabolism takes place here. Cytoplasm Function One of the major functions of cytoplasm is to enable cells to maintain their turgidity, which enables the cells to hold their shape. Other functions of cytoplasm are as follows: The jelly-like fluid of the cytoplasm is composed of salt and water and is present within the membrane of the cells and embeds all of the parts of the cells and organelles. The cytoplasm is home to many activities of the cell as it contains molecules, enzymes that are crucial in the break down of the waste. The cytoplasm also assists in metabolic activities. Cytoplasm provides shape to the cell. It fills up the cells thus enabling the organelles to remain in their position. The cells, without cytoplasm, would deflate and substances will not permeate easily from one to the other organelle. A part of the cytoplasm, the cytosol has no organelles. Rather, the cytosol is enclosed by matrix boundaries that fill up the cell section which does not hold the organelles. The whole cellular content of a living cell is called protoplasm. The cytoplasm, nucleus and all other living components of the cell together make up the protoplasm of a cell.NucleusThe nucleus is an important element of the cells. It is a membrane-bound organelle that is typically found in the eukaryotic cells. Eukaryotes usually have a single nucleus, whereas some cell types do not possess a nucleus (RBC-Red Blood Cells).

The model shows a cellular process that occurs in every cell in eukaryotic organisms.
What is the purpose of the process shown?
Answer:
The correct answer is - create polypeptide and eventually proteins for gene expression.
Explanation:
This model is representing the translation process in protein synthesis which takes place in the cytoplasm of the cell and results in forming proteins from the information carried by mRNA from DNA in a code. The translation is the process that translates the code, carried out by mRNA with help of ribosome and tRNA, into a chain of amino acids called polypeptide chain that forms eventually in protein.
1. mRNA strand and ribosome present of ER translate codes into a protein.
2. Amino acids are transferred by the tRNA molecules to the ribosomes.
3. mRNA and tRNA bases are paired and amino acids are left behind to create polypeptide.

Theodor Schwann, a German physiologist, extended Schleiden's observations to animals, stating that animals are also composed of cells in 1839.
Rudolf Virchow, a German physician, proposed that cells can only arise from pre-existing cells in 1855, completing the cell theory

Explanation:
Many natural ecosystems have been destroyed by human activity. To better manage our remaining natural ecosystems, we must first understand how the ecosystems are structured. One way to do this is to determine how the organisms in the ecosystem obtain the matter and energy they need to survive. The figure below shows a simplified food web. Use the figure to answer the following questions.
Which of the following correctly shows one pathway for the flow of energy to an owl?
A.
owls → squirrels → foxes
B.
green plants → mice → squirrels
C.
owls → green plants → mice
D.
green plants → squirrels → owls
The correct pathway for the flow of energy to an owl is from green plants to squirrels, and from squirrels to owls. Therefore, the correct statement is option D.
What is the flow of energy in the food web?This pathway starts with green plants, which are producers and can prepare their own food. The energy from the plants then flows to squirrels, which are herbivores and eat the plants. Then, the energy is transferred to owls, which are carnivores and eat the squirrels.
This pathway represents the flow of energy through multiple trophic levels in the food web, starting with producers and ending with a tertiary consumer.
However, the flow of energy in an ecosystem is important for preserving natural ecosystems. The energy that flows through ecosystems originates from the sun and is captured by producers such as green plants which then move towards food chain as organisms consume other organisms.
Therefore, the correct pathway for the flow of energy to an owl is from green plants to squirrels, and from squirrels to owls.

suggest how a dimetrodon would have to behave in order to use its sail to warm its body
Answer:
Dimetrodon (/daɪˈmiːtrədɒn/ (About this soundlisten)[1] or /daɪˈmɛtrədɒn/,[2] meaning "two measures of teeth") is an extinct genus of non-mammalian synapsid that lived during the Cisuralian (Early Permian), around 295–272 million years ago (Ma).[3][4][5] It is a member of the family Sphenacodontidae. The most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It walked on four legs and had a tall, curved skull with large teeth of different sizes set along the jaws. Most fossils have been found in southwestern United States, the majority coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, fossils have been found in Germany. Over a dozen species have been named since the genus was first erected in 1878.
Explanation:
Dimetrodon is often mistaken for a dinosaur or as a contemporary of dinosaurs in popular culture, but it became extinct some 40 million years before the first appearance of dinosaurs. Reptile-like in appearance and physiology, Dimetrodon is nevertheless more closely related to mammals than to modern reptiles, though it is not a direct ancestor of mammals.[4] Dimetrodon is assigned to the "non-mammalian synapsids", a group traditionally called "mammal-like reptiles".[4] This groups Dimetrodon together with mammals in a clade (evolutionary group) called Synapsida, while placing dinosaurs, reptiles and birds in a separate clade, Sauropsida. Single openings in the skull behind each eye, known as temporal fenestrae, and other skull features distinguish Dimetrodon and mammals from most of the earliest sauropsids.
Which statement best compares bacteria and fungi? (SC.6.L.14.6)a.Most bacteria and fungi are harmless and may be beneficial to other living things. B.Bacteria and fungi always cause infectious diseases. C.Bacteria are living organisms, whereas, fungi are not. D.Both bacteria and fungi rely on living organisms to reproduce and survive.
Answer:
a.Most bacteria and fungi are harmless and may be beneficial to other living things.
Explanation:
Bacteria and Fungi are two distinct organisms that belong to different class of organisms. Fungi are eukaryotic while bacteria are prokaryotic. Although they both exist in different life forms such as being parasitic, saprophytic etc. most bacteria and fungi species are harmless and may even be beneficial to other living things.
Bacteria and Fungi are beneficial to other organisms in the sense that they form mutualistic relationships with other living organisms. For example, certain species of bacteria helps to fix nitrogen in the root nodules of leguminous plants, while fungi forms a mutualistic relationship with algae called LICHEN where they benefit one another in a way or the other.
The statement that best compares bacteria and fungi is- Most bacteria and fungi are harmless and may be beneficial to other living things. Option A is correct.
Some bacteria are good and provide health benefits and anti-aging properties. Good bacteria help with digestion and absorption. They also boost immunity.
Examples of good bacteria include Bifidobacterium and Lactic Acid Bacteria. Bacteria that are bad have negative effects on the body.
Fungi are used by humans for a variety of purposes, including food or food preparation. Fungi are also used by humans to control pests. Fungi can also be used to make citric acid, antibiotics, human hormones, etc.
Therefore the correct option is option A.
