1. What nucleus is the final product?
Answers
Answer:
See explanation and image attached
Explanation:
Decay series refers to the sequence of natural nuclear transformations that occur in the heavy radioactive elements giving rise to a series of elements with different half lives and ending up with a stable nucleus.
The uranium-235 series is pictured in the image attached to this answer as obtained from Wikipedia. All the 12 steps in the decay are shown.

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.
Answers
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.

suggest how a dimetrodon would have to behave in order to use its sail to warm its body
Answers
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.

Explanation:
Just took the test
All the organisms such as an oak tree, a deer, and a grasshopper would undergo cellular respiration to obtain energy from its food. Thus, the correct options are A, C, and D.
What is Cellular respiration?Cellular respiration is the process through which the cell produces energy. Cellular respiration occurs in the mitochondria of the cell. This is also called as aerobic respiration.
Cellular respiration involves the production of energy in the form of ATP (Adenosine triphosphate) from the food (carbohydrate) which they consume. Cellular respiration occurs in the cells of every living organism on this planet.
