How can a mutation affect protein synthesis by a cell? do you think there are different consequences if it happens in a gamete cell (sperm or egg) versus a non-gamete cell?
A mutation affects protein synthesis by a cell by changing the instructions of genes for making a protein, as a variant can cause a protein to malfunction or not to be produced at all. Yes, there are different consequences if it happens in a gamete cell versus a non-gamete cell.
The mutation affects protein synthesis in a cell due to the involvement of genes as they are responsible for coding proteins, needed for all of the functions of the body and to build strong body structures. So, a mutation that is affecting could change the way how a protein is made.
If a mutation occurs in cells that are making gametes by the process of meiosis or during the meiosis process itself, it has the chance to be passed on to the next offspring and will contribute to the condition of genetic variability of a particular population. Mutations are considered the sole source of genetic variability that may have the chance to occur in asexual reproduction.
If a gene is made to alter in a germ cell, then the mutation will be termed germinal mutation because germ cells will give rise to gametes so that some gametes will carry the process of mutation and can be passed on to the subsequent generations.

Energy flow in an ecosystem is best represented by _______. a. the predator/prey relationship b. food chains c. food webs d. autotrophs please select the best answer from the choices provided a b c d
Energy flow in an ecosystem is best represented by c. food webs.
In the field of ecology, we can describe the food web as a representation of all the food chains of a particular ecosystem.
In an ecosystem, there are many organisms that act as prey and predators for each other through which energy flows in the ecosystem.
As a food web will represent all the prey as well as predator organisms and also depict what eats what, hence the energy flow in an ecosystem can best be represented by food webs.
Other options, such as food chain, are not correct as a food chain is a representation of a single energy flow system of an ecosystem. To determine the energy flow of the whole ecosystem, a food web is required.

Variation in intergroup relationships among species and among and within local populations of African apes-evolutionary process
despite the truth that many animals shield important sources from conspecifics at some stage in interactions, several primate species automatically have interaction in tolerant encounters. In terms of evolutionary process intergroup relationships, as an instance, African apes and people (Homininae) show off full-size range, and local human groups are hooked up thru a community of affiliative relationships amongst corporations. We have to have a look at variance between species, between populations, and inside populations to be able to comprehend this range and its evolution. even as bonobos' intergroup connections are typically affiliative, each jap and western chimpanzees often exhibit adverse intergroup ties. despite the fact that the percentages of corporations with numerous adult males within the genus Gorilla range, all subspecies show off great domestic range overlap and each adversarial and affiliative intergroup interactions. in regards to neighborhood populations of the same (sub)species, there are few variations between Pan and Gorilla. The distribution of girls within corporations seems to play a position in the affiliative relationships among bonobos, however intergroup connections differ in the identical neighborhood populations in different species. those patterns in bonobos seem like just like the ones in local human communities, wherein lady dispersal amongst corporations performs a huge function in affiliative relationships and intergroup connections vary for extraordinary combinations of companies. All gorilla subspecies showcase a variety of intergroup connections, from affiliative to competitive, and relatives relationships between leading males are vital to the development of affiliative relationships. studies on intergroup variation, the roles played through ladies and men in that variation, and the genetic make-up of the neighborhood populations may additionally assist us higher apprehend the evolutionary process that gave upward thrust to neighborhood groups within the Homininae.To learn more about the evolutionary process here:-

How do sediments eroded by water become more smooth and round
Answer: Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment causing it to become more round and smooth.
I hope this helps!
Answer:
through friction.
Explanation:
The sediments rub together to become smoother. Sediments that are transported in a mass by water or stream are in motion with respect to the motion of the stream water. They bump into each other which makes extruding parts vulnerable to getting knocked off which makes these particles round.

Sara is watching television when the power goes out. When she walks to the kitchen to get a candle, she knocks over a chair. She lights a match and holds it to the wick of the candle. She uses the light from the candle to find her way to the chair, which she picks up and sits in. Which of the events was a chemical change? *
Answer:
She lights a match and holds it to the wick of the candle.
Explanation:
Chemical change produces the required products of reactants by an irreversible reaction. For there to be a chemical change, a chemical reaction between reactants must occur.
Lighting of a match is a chemical change in which the friction between the match box and the gun powder on the stick produces a flame. This reaction produces a product by an irreversible process. After the flame burns out the wick of the candle, it can not be reversed.

Which reactant of photosynthesis is also involved in climate change?
A oxygen
B carbon dioxide
C water
D sugar
Answer:
B. Carbon dioxide
Explanation:
First of all, let’s write out the photosynthesis equation to identify the products and reactants.
6CO2 + 6H2O + energy —> C6H12O6 + 6H2O
In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.
In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.
Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.
We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.
Therefore, the best answer choice is B. Carbon dioxide
Heterozygous is another word for what?
Answer:
Heterojunction or having two identical alleles of the same gene.
Explanation:
A heterojunction is an interface that occurs between two layers or regions of dissimilar semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. It is often advantageous to engineer the electronic energy bands in many solid-state device applications, including semiconductor lasers, solar cells and transistors. The combination of multiple heterojunctions together in a device is called a heterostructure, although the two terms are commonly used interchangeably. The requirement that each material be a semiconductor with unequal band gaps is somewhat loose, especially on small length scales, where electronic properties depend on spatial properties. A more modern definition of heterojunction is the interface between any two solid-state materials, including crystalline and amorphous structures of metallic, insulating, fast ion conductor and semiconducting materials.

phylogenomic analysis of the parrots of the world distinguishes artifactual from biological sources of gene tree discordance
The correct answer is heterogeneous levels of phylogenetic signal among individuals within datasets may cause artifactual sources of topological discordance.
Individuals with varying levels of phylogenetic signal within datasets may be artifactual sources of topological discordance. We investigated how the information content of tips and subclades influences topological discordance in the parrots (Order: Psittaciformes), a diverse and critically endangered clade of nearly 400 species. We estimated concatenated and species trees for 382 ingroup taxa using ultra conserved elements from 96% of the clade's species-level diversity. We discovered that discordance between tree topologies was most common at nodes dating from the late Miocene to the Pliocene, and frequently at the taxonomic level of genus. a better predictor of metrics supporting alternative topologies.
