Which of the statements are true? Cell membranes in cold tolerant winter wheat plants have a higher ratio of unsaturated fatty a

cids to saturated fatty acids than do cold intolerant wheat varieties. A plant that produces more monounsaturated fatty acids than polyunsaturated fatty acids in its membranes in winter has an increased resistance to freeze damage. Cell membranes in reindeer legs (near the hooves) are kept flexible because they have a large number of saturated fatty acids. Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance.

Answer:

Option-1 and 4

Explanation:

Fatty acids can be distinguished into two types: saturated and unsaturated fatty acids.

The saturated fatty acids are the fats that do not contain any double bond as a result of which they are tightly packed and are found in solid-state whereas unsaturated fatty acids are the acids that contain double bond in their structure and are found in liquid form.

The cold-tolerant species show an adaptation to survive in cold species by modifying their cell membrane composition that is they increase unsaturated fatty acids which help in maintaining the fluidity of the cell membrane.

Thus, in the given question option-1 and 4 show, this adaptation and are true options.

padilas [110]

Answer:

Genotype ratio Tt:tt=1:1

Phenotype ratio 1:1

Explanation:

the phenotype ratio should be 1:1 since there are 2 individuals with the dominant allele and 2 without it

The genotype ratio should be 1:1 for the same reason

Many genes are involved in coat color and coat patterns in cats. The autosomal Dominant white (Wd ) allele results in pure-white
dsp73

Answer: The parents of the white cat would be a dominant white cat and a recessive colored coat cat.  The parents of the autosomal tabby would be a dominant tabby and either a recessive brown cat, striped cat, or a recessive black cat.

Explanation:

The genotypes and phenotypes would be : WW- Dominant white and ww- recessive color coat cat; their offspring would be 100% recessive white kittens

TT- dominant tabby and a recessive brown cat; their children would be 100%- dominant brown tabby

TT- dominant tabby and a recessive striped cat; children would be 100%- brown striped

TT- dominant tabby and a recessive black cat; children would be 100%- tabby kittens

Which of the following statements about the equilibrium theory of island biogeography is FALSE?
Ksivusya [100]

Answer:

b) At equilibrium, the species composition of an island will not change.

Explanation:

The Theory of Island Biogeography written by Robert H. MacArthur and Edward O. Wilson (1967) is an essential book for any professional working in biogeography, biodiversity, ecology, conservation and related fields. The theory of island biogeography states that species diversity on islands tends to approach a dynamic equilibrium due to the balance between colonization (inmigration), speciation and extinction. At equilibrium, the species composition of an island will change, precisely at the time that immigration and extinction processes maintain the number of species in a dynamic equilibrium, thereby maintaining species diversity. In this case, the colonization rate represents a function of distance to the continent (or other islands), the extinction rate is a function of the size of the island and habitat heterogeneity, and speciation is a function of time. This book also contains a series of useful considerations: 1-the number of species in an area is directly associated with the size of the area; 2-large islands support more diverse communities than small islands; 3-the viability of populations on island systems can be considered as a function of the island size and its proximity to the mainland (or other islands); and 4- when a habitat is lost the remaining fragmented area may lose some of its important species.
