Define the term hominin.
Answer:
a primate of a taxonomic tribe ( Hominini ), which comprises those species regarded as human, directly ancestral to humans, or very closely related to humans.
I hope it helps

✭The Hominini, or hominins, form a taxonomic tribe of the subfamily Homininae ("hominines"). Hominini includes the extant genera Homo (humans) and Pan (Chimpanzees and Bonobos), but excludes the genus Gorilla (gorillas).
✭The term was originally introduced by John Edward Gray (1824), long before any details on the speciation of Pan and Homo were known. Gray's tribe Hominini by definition includes both Pan and Homo. This definition is still adhered to in the proposal by Mann and Weiss (1996), which divides Hominini into three subtribes, Panina (containing Pan), Hominina ("homininans", containing Homo "humans"), and Australopithecina (containing several extinct "australopithecine" genera).
FOLLOW ME ♥️Which statement BEST describes the cell membrane in a typical bacterial cell? The membrane...
a)has the same permeability to all substances moving in and out the cell.
b) selectively controls what enters and exits the cell.
c) is composed of two protein layers with lipids floating inside.
d) is composed of protein and carbohydrates only.
Answer:
Explanation:What’s a cell? Well, on some level, it's a bag of goo. The plasma membrane—the outer boundary of the cell—is the bag, and the cytoplasm is the goo.
Of course, a cell is ever so much more than just a bag of goo. It's a complex, highly organized unit, the basic building block of all living things. And the plasma membrane and cytoplasm are actually pretty sophisticated.
The membrane is a delicate, two-layered structure of lipids and proteins, and it controls what can enter and exit the cell. Similarly, the cytoplasm of a eukaryotic cell consists not only of cytosol—a gel-like substance made up of water, ions, and macromolecules—but also of organelles and the structural proteins that make up the cytoskeleton, or "skeleton of the cell."
In this article, we’ll take a closer look at the plasma membrane and cytoplasm.
The plasma membrane
Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
A phospholipid is made up of a hydrophilic, water-loving, phosphate head, along with two hydrophobic, water-fearing, fatty acid tails. Phospholipids spontaneously arrange themselves in a double-layered structure with their hydrophobic tails pointing inward and their hydrophilic heads facing outward. This energetically favorable two-layer structure, called a phospholipid bilayer, is found in many biological membranes. [Close-up of a phospholipid]
As shown below, proteins are also an important component of the plasma membrane. Some of them pass all the way through the membrane, serving as channels or signal receptors, while others are just attached at the edge. Different types of lipids, such as cholesterol, may also be found in the cell membrane and affect its fluidity.

What is the difference between reproduction and heredity?

producing offspring
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Reproduction always involves changes in inherited characteristics, whereas heredity
does not
Heredity always involves changes in inherited characteristics, whereas reproduction
does not
Answer:
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Explanation:
PLEASE MARK BRAINLIEST, if you think this is correct and best! Thanks!
Reproduction generally means making copy of something, like giving birth/breeding, duplicating.
Heredity is inheritance of traits/ passing on traits from parents t thsir child/children through genes. It makes children have same traits as their parents and looks so what same like their parents!
They definitely aren’t same!
Reproduction is the process of producing offspring, whereas heredity is the process of passing on traits.
What do you mean by heredity?Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information.
Heredity explains why offspring resemble, but are not identical to, their parents and is a unifying biological principle. Heredity refers to specific mechanisms by which characteristics or traits are passed from one generation to the next via genes.
Heredity can be defined as the transfer of genetic characters from parents to offsprings by the process of fertilization, where the nuclei of male and female gamete fuses with each other and forms the genetic material of the zygote.

Answer:
With the boost in warmer weather and excess water, populations will boom
Explanation:
Yabbies will do best at a water temperature of between 12°C and 20°C but they will tolerate water that is a little colder or warmer. Complete immersion in water is not essential for life for the yabby. If its gills are kept moist (humid air is sufficient), it can absorb oxygen from the air and survive for many days out of water. To breed, however, it must be in water. With the water needed for breading and warmer weather used for breeding, population numbers for the Yabbies should rise.
How many cells does one gram of yeast contain?
Answer:
20 billion cells
Explanation:
It is based on the assumption that there are 20 billion viable yeast cells per gram of dried yeast. While there are 20 billion cells, you'll find that many manufacturers will state other numbers on their products.
The number of cells that one gram of yeast contain is 12 billion cells.
What are yeast cells?Yeasts are found in soils and on plant surfaces all over the world, and they are particularly prevalent in sugary environments like flower nectar and fruits.
It is predicated on the idea that each gram of dry yeast contains 12 billion live yeast cells. Despite the fact that there are 12 billion cells, several manufacturers will list different quantities on their products.
As opposed to mushrooms, yeast is a fungus that develops as a single cell, according to Laura Rusche, an associate professor of biological sciences. Although there is just one cell in every yeast organism, these cells form multicellular colonies.
Therefore, Yeast has 12 billion cells per gram.

Some behaviors, such as nest building in birds, are determined by the genes of an organism. These innate behaviors are inherited from parent to offspring and exhibited even if the offspring does not observe its parent performing the behavior. Nest building behavior was most likely an evolutionary advantage because birds that built nests were more likely to raise their young to maturity and thus increase their reproductive success. That is, birds that laid their eggs in nests had more offspring survive to adulthood than those that did not. Behaviors that are determined by genes and that give an organism increased reproductive success usually become common in a species due to+
Answer:
natural selection
Explanation:
According to the evolutionary theory, natural selection can be understood as the process of differential survival and reproduction of individuals due to phenotypic differences, which may be associated with different colors, sizes, behaviors, etc. The only prerequisite is that these phenotypic differential traits must be heritable, which means that they must be passed by genes from one generation to the next. For example, in the white-throated sparrow, it has been discovered two morphs that differ in behavior due to a chromosomal inversion in sex chromosomes.

Answer:
Just like living organisms, viruses use genetic material such as DNA or RNA, but unlike living things, they cannot reproduce using mitosis, binary fission or meiosis.

Answer:below

1,455,000 mg
145,000 mg
1,450 mg
1.45 mg
O
145 mg
Grams can be converted into milligrams by multiplying the amount in grams by 1000. Therefore, 1455 grams will be equivalent to 1,455,000 mg. Thus, the correct option is A.
The conversion of metric units from one unit to another can be done by multiplication or division by powers of 10. If the unit is to be converted into a bigger unit, it has to be divided, whereas if the unit is to be converted into a smaller unit, it has to be multiplied.
Thus, the conversion of gram to milligram is conversion of a unit into a smaller unit and the amount, therefore, has to be multiplied.
There are 1000 milligrams in 1 gram. Therefore, 1,455 grams will have 1000 × 1,455 = 1,455,000 milligrams.
