Answer:
1) A mutation appeared in one weed plant that made that weed not susceptible to the herbicide ( B )
2) The weed will survive long enough to reproduce ( B )
Explanation:
1) The most likely reason the weed remained is : A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
The weed plant must have undergone some mutation in order to be resistant to the herbicide which would kill the weed before now
2) The most likely thing that will happen if the weed stays in place in that farm is : The weed will survive long enough to reproduce
The trait or mutation of the weed cannot just spread to other weeds nearby it can only spread by reproducing more weeds of same mutation
Answer:
D. Chemoautotrophs
Explanation:
Autotrophs in plain are organisms that synthesize their own food while hetrotrophs are organisms that do not synthesize their own food.
Chemotrophs (Chemoautotrophs and Chemohetrotrophs) are a group of organisms that obtain their energy through the oxidation of inorganic molecules, These organisms require carbon to survive and reproduce.
Chemoautotrophs are able to produce inorganic molecules by the fixation of CO2 from their immediate environment. The energy required for this process is got from Nitrogen, Magnesium, Sulphur etc.
Chemohetrotrophs are a class of chemotrophs that are unable to synthesize their own food but rather ingest complex molecules like carbohydrates from the environment.
Phototrophs are a group of organisms unlike chemotrophs that depend on the source of light or sunlight for synthesizing its food or organic molecules.
Photoautotrophs are basically photosynthetic plants which are able to carry out photosynthesis ie the conversion of CO2 and H2O to give Glucose and Oxygen in the presence of sunlight.
Photohetrotrophs are a class of organisms that do not synthesize their own food but rely on other organisms or already made organic molecules.
A result of convergent evolution are the webbed feet of ducks and frogs.
Explanation:
The evolution of the animals, or rather the development of adaptive features, works in very interesting manner. It is very common in nature that animals that are closely related do not share similar characteristics, or the opposite, animals that are not closely related but share similar characteristics. The later case, is referred to as convergent evolution, where totally different animals have developed the same or very similar characteristics in order to be better suited for their environment.
In this case we have the ducks and frogs, and the webbed feet as shared adaptations, or feature. The ducks are birds, while the frogs are amphibians, and their last common ancestor has lived hundreds of millions of years ago. Despite that, both animals have developed webbed feet, and the reason for this has been that both animals have faced the same challenge, swimming and diving, and the webbed feet help them to be much faster and more agile in the water.
Other examples of convergent evolution (in the present and in the past) are:
- Hyena - Tasmanian devil
- Sandy cat - Fenec fox
- Smilodon - Thylacosmilus
- Bats - Birds

Grass I think Bc it’s not a living thing
According to the characteristics of this organism, it is classified into the Protist kingdom, which brings together unicellular or simple multicellular organisms that do not form tissues, both autotrophic and heterotrophic.
<h3>What is the kingdom protista?</h3>
It includes eukaryote-type organisms that, due to their characteristics, cannot be included in the rest of the kingdoms of this class.
Although most protists are unicellular, there are also multicellular protists and they can have autotrophic or heterotrophic metabolisms.
Therefore, we can conclude that the protist kingdom groups living beings that have cells belonging to the eukaryote group.
