Menjawab:
a) 250N
b) 250Watt
Penjelasan:
a) Upaya yang dilakukan beny untuk mendorong gerobak tersebut setara dengan gaya yang diterapkan untuk mendorong beban. Oleh karena itu, Effort beny yang digunakan setara dengan 250N
b) Daya = Pekerjaan selesai / Waktu
Karena usaha yang dilakukan = Gaya × jarak
Daya = Gaya × jarak / waktu
Diberikan
Angkatan = 250N
Jarak = 50m
Waktu = 50 detik
Yg dibutuhkan
Power Beny melakukannya untuk mendorong keranjang belanjaan.
Daya = 250 × 50/50
Daya = 12500/50
Daya = 250Watt
Oleh karena itu, Benny menggunakan tenaga 250 watt untuk mendorong kereta belanja tersebut
There are five main fields of environmental science; each one created up of multiple smaller domains.
These five areas are atmospheric sciences, ecology, environmental chemistry, geosciences, and social sciences
<h3>What are three fields within environmental science that focus on non living aspects of the environment?</h3>
Climatology is the study of the Earth's atmosphere and climate. Hydrology is the reflection of Earth's water resources.
Earth science is the analysis of the Earth's nonliving systems and the planet as a whole.
Thus, These five fields are atmospheric sciences, ecology, environmental chemistry, geosciences, and social sciences.

Polar substances .
u havent given any option
Answer:
The metabolic capacities should be:
Bacteria that fulfill replicative cycles, have a metabolization that requires a substrate or a metabolite, coexist in extreme environments where their method of survival is sporulation.
Ability to admit genetic mutations between different bacterial colonies for their possible evolution, an ideal environment with pH, gases, and substrates according to the life of the bacterial colony, which is often called as a culture medium.
Explanation:
Temperature is essential in bacterial growth, as is the pressure and environment that surrounds the bacteria.
Something that must be taken into account is that other microorganisms coexist with the bacteria in the medium, since they can be limited to their colonization, an example of this is the gram negative and positive bacteria, coccoid and bacilloid, which generally are not compatible with the penicillium fungus, as this, as a product of its metabolization, releases a substance called penicillin that prevents the colonizing growth of other species of microorganisms such as this type of bacteria.
Answer:
3. the absence of a cell wall in human cells
Explanation:
Animal cells do not have cell walls. Cell membranes separate the cytoplasm of the animal cells from the surroundings and maintain their interior. Plant cells have cellulosic cell walls. A cell wall surrounds the cell membrane of a plant cell. Cell walls serve to provide structural support and protect plant cells from pathogens. Cell walls also help keep excess water out of cells so they do not burst. Therefore, human cheek cells would not have cell walls while the onion cells would have cell walls made up of cellulose.
