Answer:
A universal common ancestor (UCA).

Explanation:
According to Darwin, all life on Earth evolved from a universal common ancestor; that is, the very first organism on Earth. If you pick any living plant or animal on Earth and trace its lineage back far enough, billions of years ago, you will eventually find the UCA. Every species on Earth is united to every other species through their connection with the UCA.

The UCA itself was probably a single-celled organism of some kind and died about 4.1 billion years ago. But through it, every species, be it human, dog, tree, or mushroom, shares this one ancestor with everyone else.

Species also have what's called a lowest common ancestor with each other, much more recent than the UCA. For example, the LCA between humans and chimpanzees probably lived and died around 4 million years ago.

The diagram is a tRNA containing the anticodon for the codon present in the mRNA with an amino acid attached.

tRNA stands for transfer RNA, which is a type of RNA molecule that plays a crucial role in protein synthesis.

tRNA is responsible for delivering specific amino acids to the ribosome during the process of translation, where the sequence of nucleotides in mRNA is decoded to form a protein.

Each tRNA molecule is specific to a particular amino acid, and has an anticodon sequence that matches the codon sequence on the mRNA.

At one end of the tRNA molecule, there is an amino acid attachment site where the specific amino acid is attached to the tRNA. At the other end, there is the anticodon sequence, which recognizes and pairs with the complementary codon sequence on the mRNA.

Explanation:

Inside a seed, the new sporophyte is an embryo. An embryo is a fertilized egg that has developed into a multicellular organism but is not yet able to survive on its own outside the seed.

The embryo is the seed's primary growth stage. The embryo is encased in the endosperm or cotyledon, which offers nutrition to the plant until it has grown enough to develop roots and leaves.The two primary groups of plants are angiosperms and gymnosperms. Angiosperms have seeds that are enclosed inside an ovary. The ovary matures into a fruit after the fertilization of the egg. On the other hand, Gymnosperms have seeds that are not enclosed in a fruit, for instance, the conifers. Instead, they are carried in cones.

Answer:

The answer is option A "4 chamber stomach = behavioral and chewing cud = internal structural"

Explanation:

Goats and other ruminants do not digest food directly as they eat their food and the reason is that ruminants do not have the enzymes that are necessary for breaking down the food directly as they eat so digestion in ruminants and particularly Goats has to undergo processes or procedures before the final digestion takes place.

All the processes in digestion for ruminant animals takes place in their four chambered stomachs which are the Rumen, Reticulum, Omasum and Abomassum.

In the four chambered stomach of Goat, the type of adaptation is behavioral and chewing cud which is the internal structure.

The presence of enzymes in the blood is advantageous for several reasons. Firstly, enzymes catalyze biochemical reactions and increase the rate at which they occur.

This means that without enzymes, the body would have to rely on slow, spontaneous reactions to perform necessary functions such as breaking down food or producing energy. Additionally, enzymes can be specific to certain reactions, meaning that they can selectively catalyze a particular reaction without affecting others. This specificity allows for more precise control over metabolic pathways, which is important for maintaining homeostasis in the body.

Enzymes can also be regulated through feedback mechanisms, where the product of a reaction can inhibit or activate the enzyme responsible for that reaction. This allows for dynamic regulation of metabolic pathways and prevents the buildup of potentially harmful intermediates.

Overall, the physiological advantage of having enzymes in the blood is that they increase the efficiency and specificity of biochemical reactions, allowing the body to perform necessary functions more quickly and accurately.

The statement is True.

The term "invasive species" generally refers to non-native species that are introduced to a new ecosystem and have the potential to cause harm to the environment, economy, or human health.

Even if a non-native species does not cause any harm, if it has been introduced by humans to an ecosystem where it is not naturally found, it can be considered invasive. This is because the non-native species may still compete with native species for resources or disrupt the natural balance of the ecosystem in ways that may not be immediately apparent.

Therefore, any non-native species that is intentionally or unintentionally introduced to a new area can be considered invasive, regardless of whether or not it causes ecological or economic harm.

The thing that happens during the carbon fixation stage of the Calvin cycle is that:

A 5-carbon molecule gains carbon from CO2 (ribulose-1,5- bisphosphate or RuBP). The newly formed six-carbon molecule is promptly divided into two 3-carbon molecules (3-phosphglycerate).

RuBP is a straightforward five-carbon molecule that receives carbon from the atmosphere through the Calvin cycle processes. These processes utilize the NADPH and ATP created during the light reactions as a source of chemical energy. Glucose is the Calvin cycle's end result.

Therefore, one of the three phases of the Calvin cycle is carbon fixation. It is a procedure that joins the organic molecule and the inorganic carbon atom.

Phylogenetic analysis has revealed that HIV has a common ancestor in SIV, and has diversified into different strains through independent emergence from SIV, providing important insights into the evolutionary history and spread of the virus. Here options B, C, and D are correct.

B - Phylogenetic analysis has shown that all strains of HIV are more closely related to each other than they are to SIV (Simian Immunodeficiency Virus), which suggests that HIV has a common ancestor that originated from SIV in chimpanzees and gorillas. The most widely accepted theory is that HIV-1, the most common strain of the virus, originated from SIV in chimpanzees and was transmitted to humans through the hunting and consumption of infected bushmeat.

C - Phylogenetic analysis has also revealed that HIV has crossed the species barrier on several occasions, as there are multiple strains of the virus that have been found in humans, including HIV-1, HIV-2, and numerous circulating recombinant forms (CRFs). These different strains have likely been transmitted to humans from various non-human primates, including chimpanzees, gorillas, and sooty mangabeys, through multiple zoonotic events.

D - Furthermore, phylogenetic analysis has shown that different strains of HIV have emerged independently from SIV on multiple occasions, leading to the current diversity of HIV strains. For example, HIV-2 is believed to have originated from SIV in sooty mangabeys, a different primate species than the one that gave rise to HIV-1.

Without any greenhouse gases, Earth would be an icy wasteland. Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space. This heat trapping is known as the greenhouse effect. ... Putting so much new CO2 into the air has made Earth warmer.

Answer:

If we don't reduce the emissions of greenhouse gasses, we will end up have climate change. As the world heats up, the water levels rise, the polar ice caps melt and costal cities will end up under water at somepoint. Also animals that can't handle the temp changes can die.
