A man is found lying in a chair. On the wall behind him is a wide, bloodstained area with a void. The droplet sizes are less tha

n 1 mm in diameter. The area of the desk is also covered with droplets of the same size. Which weapon most likely caused this blood-spatter pattern?

This might be a case of high velocity blood spatter. This type of blood stain is most likely to be caused by a gun of a small calibre.  The gunshot usually causes high velocity blood spatter or can be caused by other objects when high amount of force is exerted. The high velocity blood spatter are caused by force travelling at a speed of 100 feet per second or more which produces droplets of diameter less than 1 mm.  Explosions may also cause such high velocity blood spatter.

The cells of plants and animals are similar, except for a few different structures. Which structures are only found in plant cel
Leviafan [203]

Answer:

large central vacuole

cell wall

Explanation:

Let me clear some things up for you. There are two types of cells - Prokaryotes and Eukaryotes. The principle difference between these types of cells are the structure of their genome. In case of prokaryotes, the genomic matter do not have a defined structure, it just kind of floats around in the protoplasm. But in the eukaryotes, the genome is more structured, have all kinds of proteins associated with them, and is surrounded by a two layered sack called the nuclear membrane. Both plant and animal cells have these feature of structured nucleus, therefore, they are both eukaryotes.

Now for the difference between plant and animal cells. the features you mentioned are unique about plant cells, but do not rule them out from being eukaryotes, as the 'true' structure of the nucleus is still there. Cell walls are necessary for the plant cells because plants do not posses an endoskeleton like most of the animals do. The cell wall makes the whole plant rigid so they don't fall apart or appear like a blob. Chloroplast is where photosynthesis happens, so it should most definitely be in a plant cell. Animals don't do photosynthesis so they don't have chloroplasts. Vacuoles are also present in animal cells, but they are much smaller, greater in number, and are known as lysosomes. Functionally they are virtually the same.

You cross two true-breeding parents (one with yellow seeds and one with green seeds), grow and self-pollinate the F1 generation,
Andru [333]

Answer:

1500

Explanation:

Let's assume that the allele for yellow seed color is "Y" and the allele for green seed color is "y". Genotype of pure breeding yellow seeded plant would be "YY" and that of the green seeded plant would be "yy". A cross between YY and yy gives all heterozygous yellow seeded plants (Yy) in F1 progeny. Self pollination of two F1 plants (Yy x Yy) obtains F2 generation in 3 yellow: 1 green ratio.

The total population size of F2 generation = 2000

The proportion of yellow seeded plants in F2 generation = 3/4 (since the F2 phenotype ratio is given 3 yellow: 1 green)

Therefore, total number of yellow seeded plants in F2 progeny = 3/4 x 2000= 1500

What information on a pedigree can tell you whether a gene is a autosome or a sex chromosome ???
My name is Ann [436]

Answer:

What information on a pedigree can tell you whether a gene is on a autosome or not a sex chromosome? If in a pedigree, the occurrence of the disorder is 50/50 between females and males, then it shows that it is autosomal. If the disorder is mostly shown in males then it is a sex-linked trait.
