and mouth size of hominins? (hint: as cranial capacity increased, the use of sophisticated stone tools became more common.)

When the organism become bipedal, they walk with 2 legs so there are 2 arms that were unused. Some of them try to use that hand by grabbing stick or stone, leading to tools. They start to think more to develop tools and their brain capacity become increased.
The ability to use stone tools will help in food digestion since it can break the food easier. This reduces the needs for bigger teeth/jaw.

Help me out with this three please
Vesnalui [34]
1. I’m not really sure how to answer it, i think it’s parasitic
2. The tick is the parasite since the human is the host
3. It’s symbiosis bc it’s a long term biological interaction between two different biological organisms (the human and the tick) and in this case it’s parasitic bc one benefits off the host but it’s harmful towards the host so it doesn’t benefit each member.
Hope that helps :)

Explain with examples of each, how both physical and chemical weathering, along with erosion, can change Earth's surface.
Lena [83]

Answer:

Both physical and chemical weathering, along with erosion, can change Earth's surface as physical weathering allows breakdown of rock into smaller pieces, these pieces can be move from one place to another through water, wind or ice (erosion), and when the smaller pieces will settle down at a place, rain water can react with the soil or smaller rock pieces to form rock minerals.

For example: Running water, wind, and rapid heating/cooling allows the rocks to break down into smaller pieces or grains (physical weathering), then the small grains are transported and settled away from the source area through wind or river (erosion), and at the end the surface area exposed to air  for chemical weathering.

The sporophyte of an unknown plant species grows as a separate plant than the gametophyte. The plant produces both female and fl
N76 [4]

Answer:

The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".

Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.

They show alternation of generation in which sporophyte is the dominant stage.

The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.

The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.

The gametes fertilize to produce a diploid zygote.

The zygote divides mitotically and matures into the diploid sporophyte.
